JD Odansetron is one of the constipating ones, but there are others. I found Pramin worked for me. Keep on top of nausea and constipation, and be very conscious of them interfering with you nutrition and hydration. We will harp on about it but its critical to keep your intake up.

Food is a funny thing. I found a couple of things worked for me. I had to visualise eating it, geting it clear in my head that this thing was ok to eat and wouldn't hurt me. I had strange cravings, they came and went. I found things that always taste the same were good. Like KFC potato and gravy, or a hotdog (minus the bun). Every time you've ever had one of those they have always tasted the same, and when it smells right and looks right you can sometimes override the taste that says its not right. Chicken and corn soup was a staple for me. Experiment with different things, you'll have some setbacks but the little victories will make life better than forcing down Ensures all day.
