I'm sorry that you're having so much trouble finding a PCP in NJ. I would recomend visiting the following website and contacting one of the bariatric surgeons listed and inquire with them as to a LAP-BAND® friendly/knowledgeable PCP.

I would recommend my former PCP in the Lawrenceville/Princeton area but I know that's too far for you to travel. By the way, her name is Dr. Shari Diamond. She's a great PCP and was the one that diagnosed me with PCOS about 6 years ago.
Good luck!
