I have the PPO plan. I'm actually in NY, but the plan is from CA. My doctor is George Fielding at NYU in NY. My weight when starting this whole process was 256... after almost completing the liquid phase, I am down to 242. I'm 5'5", so yes it's 100 lbs overweight - I can't even imagine being able to get down to 175 - it's been so long.
Good luck to you - will keep you posted!
