Hi Tina, I can't answer your questions, but want to welcome you to the baord. My think is that if you lost 68 lbs before, you can do that and more again. I have not seen it, but I have heard that there is a specific part of this forum for those who's goal is to loss 100 lbs or more. I have certainly heard, that with weight loss, often the associated health problems subside.

Anyway, I am sure someone will point you in the right direction on your questions.
