I had my RNY on 10/7/14 and have lost 86 lbs!!! I am super excited about that and I feel so much better. I have hit a wall though and have not lost anything in almost a month. I try to eat right and I work out 3-4 times a week. I don't know if I am adding muscle which is why I hit a wall, my thyroid could be low again, or am I messing up somewhere. Any one else go through this?
