Scuppy

I was sleeved on Sept. 18th. I didn't have too much pain and was walking right away. 3 weeks after my sleeve I had another surgery, I had a harder time recovering from that but again got back to walking. I get my water and protein in daily, I have only thrown up once and that was just a few weeks ago. I started out at 248 and lost quickly at first, however now......I haven't lost any weight in 3 weeks and even went up 2lbs! My hair is falling out too which is actually less of a concern to me than the stall in the weight loss. HELP! Has anyone else experienced a stall like this??? What do you do to get moving again? Fear has really set in, it reminds me of how hard it was to lose before my surgery.
