How long will I keep losing?

Hey ladies, Got a question, I am 5 month out, as of the 18th of this month and I have lost 94 lbs, as of last Friday. I started off at 303 and I am down to 209....YEAH BABY!!!! I was wondering if or how long will I continue to lose? I mean I want to be one of those people that that have a hard time to keep weight on, ya know? My friend that had it done, 2 years ago says that she lost steadily for the first 18 months, which is awesome! She said that it could be realistic to get to 140 -150 lbs. I would LOVE that. Then I have people say weel you have lost 94 lbs. you WILL stop losing soon.....HELLO, I sure hope not! I didn't have my guts rerouted to stop now, ya know? I am kind of confused any advice or thoughts? Chell
