Is Combining Melatonin, Benadryl, and Robitussin Excessive for Sleep?
At 17 years of age, standing 6'2" and weighing 208 pounds, I am a Caucasian male living in the USA; I currently have no prescriptions and do not smoke. **Background:** Yesterday morning, I began experiencing flu-like symptoms that started with a sore throat and quickly escalated to include chills, a fever, and nasal congestion. Besides this, I've been grappling with mental health challenges for a few months, having begun therapy recently. Emotionally, I often feel pretty down, struggling to find joy unless I'm actively engaging in distractions. The night prior to feeling unwell, I had a particularly distressing argument with someone close to me. Today, my visit to the doctor yielded negative results for all tests, including strep throat, flu, and mono. Although I don't have any formally diagnosed mental health issues, I’ve read that emotional stress can sometimes manifest physically, which leads me to ponder whether that's affecting my current situation. Apologies for the long explanation; essentially, I'm quite eager to fall asleep right now, hence my decision to take something to ensure quick slumber. I did come across an old prescription for Percocet while I was feeling really ill with the flu, but I felt it was important to respect my parents and not use it without their knowledge. Getting back to the topic at hand—I took 20 mg of melatonin, 20 mL of Benadryl, and 10 mL of nighttime Robitussin. Should I expect to have a restful night, or have I potentially made a mistake? I did some research and discovered that the typical maximum dosage for melatonin is around 10 mg, but I'm hopeful that it won't lead to any serious repercussions.

Combining melatonin, Benadryl (diphenhydramine), and Robitussin (dextromethorphan and/or guaifenesin) for sleep raises some safety and effectiveness concerns. While your desire to find restful sleep is understandable, the doses you've taken are higher than generally recommended guidelines. Here’s a breakdown:
Explanation:
-
Melatonin: While melatonin can help regulate sleep, most recommendations suggest a maximum of around 10 mg for adults, though some may tolerate higher. At 20 mg, you may be taking more than necessary, which could lead to side effects like daytime drowsiness or impaired concentration.
-
Benadryl: This antihistamine is often used as a sleep aid, but 20 mL (which is about 50 mg) exceeds typical doses (25-50 mg) for adults. Excessive amounts can lead to significant sedation and potential side effects like dry mouth, dizziness, or confusion.
-
Robitussin: Depending on its formulation, nighttime Robitussin may contain ingredients that could compound the sedative effects of Benadryl, leading to increased drowsiness or confusion.
Next Steps:
-
Stay Hydrated: Flu-like symptoms can lead to dehydration. Drink plenty of fluids to help your recovery.
-
Monitor Yourself: Pay attention to how you feel. If you experience unusual symptoms such as severe drowsiness, confusion, rapid heart rate, or any difficulty breathing, ensure someone knows and can assist if necessary.
-
Sleep Environment: Create a calming sleep environment. Dim the lights, reduce noise, and keep the room at a comfortable temperature.
-
Leave Percocet Alone: It's commendable that you want to avoid taking medications without your parents' knowledge. Percocet is an opioid and should only be taken under careful medical guidance.
Moving Forward:
For your sleep and overall well-being, consider discussing your recent emotional stress and symptoms with your therapist or a trusted adult. It's critical to address both physical and emotional health without relying heavily on medications.
If you continue to struggle with sleep or your emotional well-being, plan to discuss these challenges with a healthcare professional for tailored advice. Remember, caring for your mental health is just as important as caring for your physical health.

Understanding Patchy Discoloration After Sunburns
I’m a 27-year-old female who has been diagnosed with PCOS and struggles with a vitamin D shortfall. In hindsight, I discovered an occurrence while reviewing some older pictures from a few years back. I’ve noticed that after experiencing sunburns, I occasionally develop these unusual white patches on my skin. It’s quite puzzling since this has only surfaced a handful of times. I typically make it a point to avoid sunburn, so I'm not often in this situation, but it’s interesting to observe that not many others seem to have similar reactions to sunlight exposure. On the day I get sunburned, my skin typically presents a standard pink to red hue. However, when I wake up the next day, I find the color has transformed to this patchy appearance. I’m left wondering if this phenomenon is a typical aspect of skin healing or could it be related to the sunscreen products I apply?
Is a Burning Sensation from Mouthwash Common?
I've recently been using a mint-flavored mouthwash, specifically Crest's teeth whitening formula. However, it caused significant discomfort, stinging my lips and tongue to the point where I felt compelled to switch to Therabreath. Additionally, I had come across information suggesting that teeth whitening mouthwashes might harm your enamel. Therabreath also contains fluoride and mint, and while it still causes some burning, it's noticeably more tolerable than the previous brand. For a long time, I assumed this burning sensation was simply a normal part of using mouthwash, as I have experienced similar discomfort during dental visits throughout my life. To manage the sting from Therabreath, I've found that spitting it out before the pain becomes too intense has been a helpful strategy since it's not quite as severe. At this point, I am uncertain if my reaction is specific to mint or another ingredient present in the mouthwash. I have always disliked using mouthwash due to the discomfort it brings, but Therabreath is just tolerable enough that I keep using it. I'm turning to Reddit for advice first, as I would prefer not to visit my doctor only to be told that this sensation is typical and thus wasting her time. Being autistic, I sometimes find certain sensory experiences overwhelming, and it’s possible that I could just be particularly sensitive in this case.
Addressing My Sleep Concerns: Seeking Guidance
I am a 20-year-old female, standing at 5 feet tall and weighing 179 pounds, residing in the United States. Throughout my life, I have encountered more challenges with sleep than many of my peers. In my younger years, I was known to sleepwalk and talk in my sleep quite often. Additionally, I experience particularly intense nightmares. Lately, I've noticed alarming symptoms such as waking up with a racing heart. On occasions when I don't awaken, I've had instances of bedwetting. In an attempt to alleviate this, I've begun to refrain from drinking anything for four hours prior to sleep. Despite these efforts, I find this situation concerning, especially considering my history of sleepwalking and talking during the night. Could this be a reaction to stress, or do you think I should seek professional medical advice?
Experiencing Unexpected Breathlessness One Month After Gallbladder Surgery – Should I Worry?
A 26-year-old woman, weighing 44 kilograms and standing at 5 feet 4 inches, does not smoke or drink. A month has passed since I underwent laparoscopic gallbladder removal, and while my recovery has generally been smooth, I've faced some bouts of fatigue. However, today I encountered something alarming: I felt a sudden shortness of breath after ascending a flight of stairs, which struck me as unusual. Later, while trying on outfits for an upcoming event, the same thing happened again—I became breathless. After some online research, I stumbled upon information regarding pulmonary embolism, which left me feeling quite frightened. Could this be a serious issue? Should I consider consulting my surgeon for further advice?
Experiencing Intense Night Sweats?
I’m a 22-year-old female, weighing 120 pounds and standing at 5’4”. I've had a history of post-viral illness, polycystic ovary syndrome (PCOS), and major depressive disorder (MDD). Throughout my life, I've dealt with intermittent night sweats, but it has escalated recently—in the last month or two, I've been experiencing them nightly. I've tried switching out my bedding, adjusting the temperature in my bedroom, and a few other strategies, yet I still wake up drenched, as if I’ve been sprayed with water. My clothes are soaked, my hair feels greasy and wet, and it leaves me feeling quite uncomfortable. To avoid ruining yet another pair of pajamas, I often opt to sleep without any clothes for the remainder of the night. Because of my other health issues, I undergo blood tests fairly frequently—about three to four times a year—and my physician hasn’t indicated any alarming results besides addressing those tests specifically. What could be causing this? It’s incredibly frustrating to wake up at 3 a.m. every night feeling like this.
