1 AnswerChemistry6 years agoI have trouble staying asleep....?
So lately, for the past few days I have had trouble staying asleep. I don't know what it is but I wake up sweaty in the middle of the night and have a hard time going back to sleep. Sometimes it gets so bad to the point where I turn on the TV to see if it can get me sleepy but it doesn't. And since it doesn't work and I'm a high school student and I have to wake up early then I kinda just have to THINK myself to sleep. Um, I don't know if it's something serious....I think it is but any advice?
