Has anyone else had extreme muscle weakness after sleeve surgery. Mine started at about 3 mos. post op. I don't exercise much because it's uncomfortable and makes me extremely tired. My surgeon said I must exercise, and I will feel better after I do. I was doing well with the weight loss, but am now starting to crave things that I shouldn't have. Trying like crazy to get enough Protein through food and shakes, but still feel weak. Anyone else have this problem. I feel like I'm falling apart. I am 64 years old.
