I am feeling a discourage because I had my surgery 10/18/2012 & I was 225lbs. Today I am 162 & 7months post op. I am having major weight stall & I wanna get to the 100lb mark.

First off, look at the success so far - you are 7 months out, and you've lost 63 lbs, or if you average it across 7 months, you've lost 9 lbs a month! You're making progress, and I'll bet if you look at the clothes you wear now vs. what you wore at 225, you have dropped a fair number of sizes, right?

Now, you're in a stall. What's your diet like? Are you getting exercise, and what kind/how much? Still getting plenty of Water?
