diagnosed with uc 27 years ago. Enojoyed 20 year remission with just minor blips here and there (approximately 16 of those years without any meds)
In a flare for 2 very long years which Asacol didn't help at all. Finally in remission again since Jan 2008, can't believe it..............
currently on Sulfasalazine 2 tabs 3x day. Folic acid, mesalamine enema 2 x a week. Omega 3, Probiotics, multi vitamin, calcium supplement, Biotin....
