NEWBIE - please help me....

Hi everyone! My Name is Dawn and I am from Duncombe, Iowa. I am calling a local surgeon tomorrow and asking what i have to do to get the ball rolling on a gastric bypass. I am 30 yrs old and weigh 304 lbs. I was diagnosed with diabetes 2 yrs ago and have been struggling with insuline and oral meds ever since. I am a little different than some on this site as I have already had weight loss surgery that was unsuccessful. 7 yrs ago i had vertical banded gastroplasty surgery. This surgery, as you might already know, leaves the rest of your stomach SCREAMING for food while the little pouch at the top slowly leaks the food down into it. The hunger pains were terrible, and i was wondering if any of you that have had the gastric bypass suffer severe hunger pains? I have been told by some that this surgery does something to help that side effect. My worst fear is of going thru all the pain and money involved with another surgery..just to fail again. Any info, advise or anything else that you all could give me would be GREATLY appreciated. My cousin is going to have this procedure done also, and we were going to try to coincide our surgeries so that we could do the support groups/physical therapy and exercising together... does that sound like a good idea??? ~awaiting all opinions (any iowa gossip would be good too )
