It took the doctors over 4 years to figure out I had IBS. I was relieved to finally hear something was actually wrong with me and I wasn't just making it up.the problem I've been having is finding a medicine that actually works 50% of the time. I have IBS with Gastritis which means i'm also on acid reducers, but for my IBS all i've been given to try (of course not together)is Bentyl and Levsin. Both only worked for about 6-8 hours of my acutal day. before the medicine i had IBS with D after i started taking the meds i have IBS with C.Can anyone shine alittle bit of light on the subject of meds and what seems to work well for you?
