Mine was done May 11th and I was around your BMI. While I try to sip water all day I don't come close to enough water or protean (about 2, 10g shakes at the most). first couple weeks my pee was very dark (dehydration) so I had to force down some more water, I could not do that until the doc put me on Nexium to get rid of the heartburn. I will say that over just the last few days something has clicked, I ate a little bit of spaghetti sauce with hamburger last night with a small piece of bread and am drinking coffee right now (don't drink coffee if you're dehydrated), and had my first beer yesterday (don't drink beer if you're dehydrated). Energy was, and is, a problem, I love the Energy Strawberry Crystal light (has B12 in it). Bottom line is that it sounds like all of us have gone through different levels of what you are going through but most folks get through it after 1-2 months post op, some longer some shorter. Hang in there, void something like a leak or something that went wrong during surgery, it will get better.
