I start my 3rd week tomorrow I haven't lost 1 lb And anything I eat nothing makes me sick my stomach is a little bloated today, can that be a sign of a leak? Why does nothing make me sick? I'm freezing, and still weak but why am I not losing???

It is very common for people in weeks 3 and 4 to stall and not lose any weight. I think it is because you lost weight quickly after surgery and your body needs to "catch up" to all the significant changes and the trauma from the surgery. Don't worry about it, keep following your doctor's program for Protein, Water, and exercise and you will be back on the losing track in no time!
