I had my sleeve on 8/16. I'm a male, 6'6", and on that day I weighted 387. Today (8/25), I'm at 362. I'm obviously happy with the progress, but I'm battling lightheadness and I think it's related to lack of protein. (If I drink half a shake or so, it clears up a bit later.)
I had the procedure done at UCLA & the post-op guidance was 80-100 grams of protein as tolerated, and 64oz of water. This past week I haven't had any issue with either. In fact, I'm wondering if I should increase my protein intake to combat the lightheadness?
