"i have trouble sleeping. i don&#039;t like taking drugs but find after missing 2-3 nights in a row i have to take something.  a friend (battling cancer) told me melatonin helped her. i have taken it 3 nights in a row and slept 10 hrs, 6 hrs and 8 hrs. but i seem to be drowsy midday and need a nap as soon as i get home. so going to stop for a few nights and then try half a tablet"
