I think if I hadnt still been on such a high dose of pred my nausea couldve been worse. But oh yes, I was nauseous. I also have to say, I may have a colostomy, but I am frequently with the big D. After surgery, I had alot of it. In fact, mine is still so bad, I just tell suppliers I have an ileo because thats what my output is like.
You really need to watch what you are eating to begin with. Can you give us a low down of what you are eating? Also, how much liquid you are drinking? You may think drinking water will help, but you may need to drink powerade on occasion, or something like it to help. Dehydration causes big D, which leads to more dehydration, and on we go!
