Gastric Bypass Patients

I had gastric bypass surgery 6 1/2 years ago and have, fortuntely, kept the weight off. Gastric bypass is still fairly "new" and there isn't a lot of information out there about the post-surgery time/effects past the first few years. I find that I am always experiencing changes - can eat broccoli one day, and the next it makes me sick, etc. Would love to start a thread, or a friend network here on MFP that provides that little extra support for gastric bypass patients. Thanks!
