Hello sarahshapiro: This appears to be your first posted thread here on PC. So... welcome to PsychCentral.

We here on PC can't make recommendations regarding medical concerns although, perhaps, other members may have had weight-loss-plan experiences they can share. Beyond that this is something you may want to discuss with your doctor or other medical provider.

There is a health support forum, here on PC, where members can post with regard to physical ailments, illnesses & other similar concerns. Here's a link to that forum:

I hope you find PC to be of benefit.
