insomnia
"Am 90 year old male with enlarged prostate using 5 mg Zolpidem tartrate per night along with 1/2 PM pill..Getting up about twice per night for urination but never getting more than 5-6 hours of sleep per night.Tried 10 mg Melatonin  with no other sleep aid and did find it put me to sleep easily but had to get up to pee 4 times...  between 9PM and 4 AM... Doctors these days are trying to minimize use of Zolpidem( generic Ambien) and replaced the initial  prescription from 10 MG Zolpidem, which worked very very well   for me, with 5 MG, which is noticerably less effective.. so, tried  Melatonin..This is third night with only Melatonin  and between 9PM and 2AM, I was awakened for 3 pee trips..Will go back to Zolpidem and PM pill combination."
