interstitial cystitis
"Diagnosed with IC March 2015, by ER Physician. I went to a Uro/Gyno and was given Elmiron 1 pill 3x per day and Hydroxyzine 25 mg 1 pill 3 x per day. Works 100% for me. I drink/eat what ever I want, including drinking coffee and eating chocolate. 

I have great insurance, so cost is not a problem. I have not experienced nausea, vomiting or hair loss.  Please try it, it might be the answer you're looking for."
