dear sayedji, if your diagnosis of ulcerative colitis is a proven one, then unfortunately it is such a disease which can be kept under control with medicines and not be cured fully. so you have to take medicines continuously as prescribed by your colorectal surgeon or gastroenterologist. Its the same like patients having Diabetes or Hypertension (high blood pressure) where the patient has to take medicines throughout to keep the disease in control. So I advice all my patients not to shy away from medicines and consider it as one part of their daily routine life. whenever the severity of the symptoms increase, you may have to increase the dose of asacol and if required add some more medicines as directed. Try and avoid foods which have GLUTEN. you can google it. take care wish you good health
