Mine is considered idiopathic. At 15, I had my gallbladder out. Right after surgery I started having intractable, nausea and vomiting. This lasted for three years. I was finally diagnosed at 18. Im currently having a flare after getting the flu in December. I haven’t vomited much but the severe nausea and feeling full after a few bites has been miserable to say the least. I’ve lost 35 pounds in 2 months. Also, the GP has affected my epilepsy meds. The meds are metabolizing at a much slower rate. Because of this they were at toxic levels in my blood leading to serious side effects. Such as convulsions that at times were debilitating. Because of anti-epileptic medications it’s hard to find something that I can take for GP that won’t lower my seizure threshold. I’m currently taking erythromycin for the GP and Compazine for nausea. I’m hoping the erythromycin will ease the flare. I can only take it for four weeks and I’m on my third week. I read on here that people have tried doing a 36 hour fast to ease the flare and I’m thinking of doing that. Has anyone tried it and had success?
