I was diagnosed with IBS many years ago. It would consist of intense pain for several hours, then a BM. I was never given anything for it. I haven't had an attack for about a year. This past Monday I was up all night with the pain, went to the doctor in the morning and he gave me Levbid .0375 mg which I take once in the a.m. and once at night. I am still having bad pains and getting very little sleep. Any suggestions would be appreciated.
