Hi, just been diagnosed with IBS-C/D recently. Find it all frustrating but have put in alot of research hours to get myself in a more controlled lifestyle.My GI gave the typical low down on IBS and prescribed Mebeverine for anti-spasms spells. I sometimes get bad side effects, ie headaches and nausea. Does anyone else eperience this. If not, what anti-spasm painkiller do you take?I am not happy with taking painkillers. But I don't have much choice when the pain in unbearable. I've read alot of posts and am overwhelmed with the amount of drugs/supplements people take. Does it concern you that you become too dependent on this. I understand how stressful and uncontrollable IBS is, believe you me I have had my moments at work especially when i work in a support area and need to quickly excuse myself to use the loo.Does any know of any medical reason why you should not take too many painkillers apart from being dependent on it.Tiramisu.
