Insomnia
"I am over 50 and I no longer get the amount of sleep that I used to.Went from 8 hours to now I&#039;m lucky if I get 5 hours and it&#039;s interrupted sleep.
I tried prescription sleeping pills once, but they had nasty 
 side affects
Melatonin really helps. If you take too high a dose( larger than 3mg) you will wake up with a headache
I  break a 3mg pill in half and take it"
