Amari,
Try Isopure from GNC. It is a 16oz bottle containing 40g of protein. The taste is ok and it sugar free and low carb. I sip mine thru out the day.
I was banded on the 14th also. Everything went great. Went in at 10:30 out of recovery at 1 and went home at 3:30. Dr was impressed with how well I done. I haven't had alot of gas pain. Alot of soreness around port site, but it seems better today.
