Hi:I'm fairly new to the board AND to the wonderful world of IBS. Like you, I've been dx'd by a GI after going thru ALL the tests. I've also been a chronic anxiety/ PD sufferer off and on for many years, although the full blown GI symptoms came on over the last 6 months when a recent bout of PD started up again. I've used BZD's occasionally when the anxiety problems have flared. Very familiar with their use. My BZD of choice is Klonopin because of it's long half life, etc. but I think Xanax is an excellent drug as well (when used properly). My Q to you is you mention how the Xanax helped clear up the D you had. I'm wondering if there were any other IBS symptoms that it helped with as well. At first with me D was a strong symptom. However, with diet changes, etc. D is really a small part of my current symptoms Right now I'm struggling with cramping, intestinal gurgling, frequent BM's (formed) and queasyness/nausea which drive me NUTS! Just wondering if Xanax helped you with any of these (if you were experiencing them) Thanks for viewing.
