interstitial cystitis
"Sure glad I researched and found this medicine. All others were awful. I do warn you though that Elmiron takes about 2 months to work and I have to continue taking it forever. I usually give up on medicines if they don't work in a week, sure glad I gave this a chance.  There are zero side effects.  You must follow directions about taking an hour before eating and you must stay away from alcohol and caffeine religiously.  I found that if I stay away from irritants I can decrease dose to only one a day, but as soon as I have a coke or beer or chocolate I get a flare up for a month or more."
