Creon

You guys have told me about creon and was wondering were any of you in a place like me as far as losing too much that have used creon, and did it work for you. How does it work?

It's an enzyme that helps you absorb more of what you eat.

I got below goal but I knew I would have a bounce back so I opted to make sure I was getting plenty of protein and sure enough I gained 15 lbs pretty quick. Now I'm trying to loose my 5 year regain. Blech. 

I personally have never been on it, but I know many who have been, personally cystic fibrosis patients, one of my coworkers is a CF patient.  CFers have fat malabsorption issues,  while not the same as a DSer they too have malabsorption issues (different) .  essentially creon is enzymes that  increase fat absorption, taken with each meal.  it will only be temporary for you
