ISO a non milk based protein drink. I've tried nectar and it tastes like ?. The milk based isn't sitting well with me. Anyone have one that they love that doesn't have the horrible aftertaste?

I just got off the phone with my surgeon. My haital hernia is back...I?ve been telling him that for 2 months now. I had it repaired in July last year. The reflux so is bad. Meds aren?t working. I?m sleeping sitting up again. The reflux destroyed my teeth. He recommended changing from the sleeve to the bypass. He said he can do both at the same time. Has anyone else had this done for this reason? Pros/cons?
