insomnia
"I was prescribed this after diagnosis of PTSD & anxiety waking me up during the night and always having difficulty falling back asleep. I take a 1/4 to 1/2 of 25mg tab (I'm 5ft6 130lbs) and I feel the effects of tingling legs and drowsiness after about 30 min. Sleep 8-9h/night and can wake up with noises  (husbands alarm, dog moving around) as I'm a light sleeper but always fall back asleep. I've tried melatonin, gravol, benadryl and this is the best. No side effects so far...!"
