Hello, I'm a college student who has been having frequent sleepiness during the day. I get enough sleep at night usually around 7-8 hours on the average night. However I still find the need to take a nap during the day. It is common for me to be sitting in a class in the after noon around 2-3 and then have uncontrollable sleepiness. I try to stay awake, I try chewing gum, shaking my legs, or even just focus on writing notes, all of which fail. It almost feels like I'm blacking out. I've noticed some trends too. It usually is the worst around 2-3, the amount of sleep I get the night before rarely changes this, eating right before this time increases the likelihood that I'll fall asleep. I also fall asleep doing other activities during this time like reading, listening to music, or watching tv. Any tips, is this serious, how can I control this?
