Anyone falls asleep during the time you are studying for a test or doing your homework or reading your textbooks? I'm avoiding coffee. In fact, I tried coffee once, and it has no effect on me. Each time I study, I always fall asleep, and it is becoming a bad habit. So anyone knows a cure for this? I want to stay awake really badly, but my eyes want to shut. I try my best to keep them open, but with no good result, if that makes sense. Thanks!
