Lenny, I agree with the great tips that Amy gave regarding the PEG. I had a similar situation with mine last month after I got home. Additionally, I was on some pretty tough antibiotics and that seemed to affect my nausea. In fact , I had nearly two weeks where I couldn't keep anything down and had to start over with Pedialyte a little at a time and work back up to the Jevity cans. They did change my antibiotic and I was able to get it in liquid form and not crush and dilute the pill form. That seemed to make a difference. If you are on antibiotics (or any medicines) that may have some effect on your digestion and stomach sensitivity. Just a thought from a newbie!
