Have you tried adding more water then it calls for? I know this means more shake to drink but for the Celebrate ENS I drink it calls for 8 oz and I can't stomach it I make it with 12 oz of water and it goes down smoothly It's a lot more watery but that is the one thing that worked for me.
I haven't tried that yet, but that's the same thing someone else said, so I think I'll try it that way. I want to be able to tell my doctor tomorrow that I've tried everything, LOL!
