Down 103 pounds

I have lost 103 pounds since February 5th. I have about 60-70 more to go. I have had no complications other than the normal eat too much or eat to fast . I am a little nervous, my weight loss has slowed down tremendously, doues this mean this is it for me? they say I will only lose 50-70 % of my excess weight, well I am at 50%. I guess I will have to work Harder ( hehehehe). Congradulations to all!!!!!
