hey pv. do you ever try kefir? I use it everyday, I couldn't drink ensure at all, big gas, and bloating. I use kefir and orange juice mixed with papaya, and blueberries, when I make shakes, I can't drink them very often, shakes really bloat me, so I have to wake up in morn. and eliminate, have totally empty stomach, then I can drink shake, can't eat and drink shake, either or type deal. have you guys tried the papyas yet? I felt the difference in gas smell by the next day, with only eating maybe 2oz slice, try it, but being in boston area I don't know how available they are, they're plentiful here in san diego, coming in from mexico. good luck
