Is Consuming Over 500mg of Caffeine Daily Harmful?
Today, I've consumed three energy drinks along with a pre-workout supplement, totaling more than 500mg of caffeine. Despite my efforts to energize, I still feel fatigued and find myself craving more. After crunching the numbers, I became quite concerned about my intake. Is this a safe level of caffeine consumption? Aside from experiencing a slight stomach upset, I feel relatively normal.

Consuming over 500mg of caffeine daily can pose health risks, especially if you're experiencing fatigue and cravings. Caffeine is a stimulant that can temporarily boost energy, but high levels may lead to negative effects, which can include upset stomach, trouble sleeping, increased heart rate, anxiety, and dependency.
Explanation:
The general guideline for caffeine consumption is up to 400mg daily for most adults, equivalent to about four 8-ounce cups of brewed coffee. Exceeding 500mg can increase the risk of side effects. Your feelings of fatigue and cravings for more caffeine may indicate that your body is experiencing some level of over-reliance, where caffeine is not providing the desired energy boost anymore, and it may also be affecting your sleep patterns.
Next Steps:
-
Reduce Caffeine Intake: Gradually lower your caffeine consumption. Aim to limit your intake to less than 400mg per day. Start by spacing out your energy drinks and supplements.
-
Stay Hydrated: Drink plenty of water throughout the day. Dehydration can worsen fatigue, so having adequate hydration is key.
-
Focus on Nutrition: Ensure you're eating balanced meals that contain proteins, healthy fats, and complex carbohydrates, which can provide sustained energy without the jitters associated with too much caffeine.
-
Improve Sleep Hygiene: Establish a consistent sleep schedule and practice good sleep hygiene to help combat fatigue. Try to avoid caffeine in the late afternoon and evening.
-
Monitor Symptoms: Keep track of how reducing your caffeine affects your fatigue and cravings. If you continue to feel overly fatigued or if symptoms worsen, consider evaluating other potential underlying causes of fatigue, such as stress, diet, or sleep issues.
Taking these steps will help you manage your caffeine intake more effectively and support your overall energy levels. If you need further guidance or want to discuss your feelings of fatigue in more detail, feel free to reach out.

Intense Pain in Left Thumb
Greetings, I’ve been experiencing a piercing pain at the tip of my left thumb intermittently. This discomfort is situated within the thumb rather than on the outer skin. It primarily affects the underside of the thumb and surrounds the base of the nail. The pain seems to extend only to the first skin fold, specifically around the distal phalanx. When applying pressure, I’ve noticed some red streaks appearing beneath the surface, alongside the white area. I trust this explanation is clear. This issue has persisted for over a year, occurring sporadically but intensifying as time has passed. Could this be a cause for concern? A bit about myself: I am a 25-year-old female with no significant medical issues in my background. I previously smoked cigarettes for three years, transitioned to vaping, and have been vaping for six years now. I maintain an active lifestyle, frequently going to the gym and participating in various sports such as indoor football and pickleball. I don’t have any known allergies.
Persistent Need to Stretch Legs While Seated
I experience a significant discomfort when seated, particularly when my knees are bent at about a 90-degree angle. This sensation compels me to stretch my legs straight, and if too much time passes without doing so—typically around every five to six minutes—the urge intensifies to an uncomfortable level that’s hard to manage. It’s more than just a desire to fidget; fully extending my legs tends to offer the greatest relief. Adjusting my position provides some comfort, but it doesn’t alleviate the feeling nearly as effectively as a full stretch does. This issue predominantly arises when I remain stationary in a chair. Occasionally, I notice a similar feeling when I’m lying down, but these instances are relatively rare compared to the frequent occurrences while sitting. I consulted a relative who is a medical professional about this discomfort, and they suggested that it doesn’t appear to align with Restless Leg Syndrome. However, since this isn't their specialization, I acknowledge that there may be a chance of error. * What could potentially be causing these sensations? * Does anyone else relate to this experience? * Are there methods available to help manage or diminish this feeling? I would greatly appreciate any advice or insights.
Excessive Electrical Shocks Encountered
Hello everyone! This is my inaugural post here since I don't frequently use Reddit. I'm a 15-year-old male, and I've recently been experiencing an unusual frequency of electrical shocks. Whenever I come into contact with anything that is either highly charged or conductive, I receive a sharp, irritating jolt. This situation has become increasingly bothersome. For instance, I can only grasp my Mac charger by the cord and not the plug itself. I'm curious if anyone has insights into why this is happening. Please let me know; I hope it's nothing serious! 💕
Combining Ketorolac with Alcohol: Is It Safe?
Recently, I unknowingly mixed a 10mg dose of ketorolac with half a bottle of 4.5% beer. At that moment, I wasn't aware of the potential risks involved in this combination. It wasn't until I was partway through my drink that I thought to look it up. Now, I’m wondering if it’ll be fine for me to have a drink tomorrow night after stopping all ketorolac use, especially since this medication hasn’t been effective for my pain relief. To give you an idea of the timeline, I took ketorolac around 2 PM and didn’t start drinking until 11 PM.
Experiencing Numbness in the Right Arm or Leg?
Hello! I’m a 17-year-old assigned female at birth, weighing approximately 110 pounds and standing around 5 feet 2-3 inches tall. At the moment, I’m not taking any medications and I don’t smoke. Recently, I’ve been facing a peculiar issue where my right leg or arm occasionally becomes numb. This sensation only impacts my right side and never the left. It can occur at any time, both during day and night. Typically, the numbness in my leg arises when I’m lying in bed, although I also experience it randomly throughout the day. I’m curious if anyone has any insights or thoughts about whether this could be something more serious than just a problem with my posture, haha!
