Interstitial Cystitis
"Definitely helped keep me asleep, but when I woke up the next morning, the first morning void (urination) was painful from not going during the middle of the night!  Plus, I had a groggy, hangovers like feeling the entire next day.  Skipped a day to make sure the Atarax was the reason, then when I took it again, same exact thing.  It doesn&#039;t knock you out, but it does help with nocturnal.  At this point, I&#039;d rather wake in the middle of the night to void instead of waking up in so much pain with a hangover that I didn&#039;t at least enjoy getting.  Plus, holding it in increases your UTI chances, and those are doubly not fun with IC."
