Yes! I have been on TPN (IV nutrition) sence November 2011 (at home). I had the same issue..would throw up after eating. Mostly I think time has helped the most and maybe some meds but it is hard to say. I am on Nortriptyline for what they are diagnosing as cyclic vomiting and have gone up on my Florinef to 0.3 mg and have started on propranolol 10mg twice a day. I am now only doing TPN 3days a week and am planning to try and go off of it next week. TPN, while not the ideal way to get nutrition, is not highly dangerous, especially if only temporary. They wil closely monitor your electrolytes, liver function, and nutrition status while you are on it and adjust the formula as necessary. I hope you feel better soon! Good luck with everything!
