I am 6 months post op. Although i didnt make it to the 400 mark i was pretty close. At my heaviest i was 376 today i am 265. I lost over 100lbs. Im very proud of what i have accomplished so far and i know i will continue looseing. As long as you are eating right, working out, you will loose the weight. I try not to think about the numbers on the scale because it makes you obsessed. Its amazing how quickly i lost 100 lbs, because i weigh myself once a month and i did not notice the rapid weight loss. My advice to everyone on here is to not concentrate on the scale as much, manage what you eat, excerise, live your life, try new activities, become more active and before you know it you will accomplish your goal weight.
