This is my first posting and I hope some of you may be able to help. I was placed on Hormone Replacement Therapy about a year ago and my IBSD has been horrible since. My OBGYN doesn't feel the HRT is the cause but my family doctor says they have a stimulant in them. Has anyone else had this problem? (Thanks to this BB I was able to finally find proof that multivitamins do make things worse for some of us.)
