insomnia
"I have trouble sleeping. I don'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"
