hi Kayte,
Sorry to hear about your trouble. No fun!!! Having GI stuff is truly miserable, it's not like you can get away from it. did they scope you at hospital? Sounds like you could use endoscopy/colonoscopy. If you are having weight loss with this that's all the more reason. The "restart" on the system can be helpful. I had ongoing nausea, bowel issues after a round of steroids and antibiotics once (walking pneumonia) and it seemed the reset, clear out process did me good. No significant findings and symptoms resolved after the prep for scoping. But they DID scope which was good information to have considering my unresolved symptoms. I also took prescription grade probiotics after, don't know if that might help....
Feel better soon,
