I can understand how you feel when you talked about just wanting to rip out that part oi your body that is causing so much havoc. It's like that saying, if it's not working then get rid of the fucker... Of course it's not really an option....
You mentioned Carafaye - Carafate? Nausea is one of the side effects with that. How long has it been going on for? A few days? Also, any constipation being experienced? Though that particular side effect is more commonly associated with opiods, Carafate can also cause that. In rare cases, it could be bezoar formation which is basically a GI blockage. You probably don't want to hear me say this, but a chat with your docs about this would be strongly recommneded.
Actually, I just clocked on, you recently had a CT scan, so I assume they would've picked that up at the time. Sorry, should've been paying more attention.
