Like most of you I'm struggling with getting in enough water, I was sleeved on the 7th (2 days post op). However there's a protein product called pro-stat, I ordered mine on Amazon. A 1 oz medicine cap gives you 15 grams of protein. It's disgusting, I've tried both the vanilla & cherry so far. The upside is taking 4 medicine cup fulls gets you to your 60 grams of protein a day. The bottles are about $30 a each but worth the investment if you can tolerate the syrupy medicinal taste.
