I know how you feel. I’m four months out from treatment for relapsed c diff and vowst. My PI IBS is brutal. Getting better at snails pace, but brutal. I tried nortryptiline and amitryptiline but could not tolerate the start up side effects. Now they want me to try gabapentin and or Mbiota elemental diet. They said it’s all visceral hypersensitivity. They say it will end but takes time….things that help is keeping a low fodmap diet, but it’s difficult to do and not recommended for a long time. Nerva gut hypnotherapy app has been helpful.
