<p>Warning against melatonin - it made me drowsy during day time and did not help me sleep at all. I cannot take it, I am driving to/from work and working being that sleepy is a drag. I much rather not sleep. I am fine with 5 hrs though, 3 is a problem, but 8/7 is also a problem, will have a headache if I sleep that much. But I am ancient even by CC parents standards, I realize that most college kids need about 8 hrs at least. Memory topper should do it. My D. has permanent sholder sport injury and could not sleep without foam toppers (2) because of sholder pain. Foam toppers fixed the problem.</p>
