Why am I NOT loosing like YOU?!?!?!?

I am 5'3 and started at 268. I had Open RNY on 11/04/03. As of the 15th (I finally decided to only weigh myself twice a month), I was down 60 lbs, so I am down to 208. I lost about 30 lbs the first month. Then the weight slowed WAY down. Then right around Christmas I dropped 20 lbs, and then January I lost like 4 lbs. Very frustrating. I have made an effort since the first of the month to really exercise. If I can't make it to the gym, I will walk 2 miles in 30 minutes (give or take a few). I know I am losing inches because I brought a new pair of size 18 jeans on 02/08. They were tight, but the 20s were kinda baggy. Today, I can wear those jeans. The fit perfect! I know that I am a big boned person, and I know I have a more muscular build too (with what little muscle is under all that fat). So, I know if I make it to say 165 or something ...I am going to look damn good. I get discouraged reading about the huge weight loss of others. Don't get me wrong, I am very happy for them, but I feel like a failure. Plus, my hair is falling out big time! You should see my sink after I do my hair in the morning...it's disgusting! I keep my hair short and I do have some highlights to help give volume. I just pray it stops soon! Anyway, the point of the story, there are others right there with you. I understand. We are doing good! WE really are! Just keep your chin up...and know that you have a place of support! ~~Eileen~~
