Hi Frankie, I have the same surgery date as you and I started at 513lbs,,,,we are in the same boat,,,,must be a hell of a big boat,,,LOL. Yes, there can be complications but there can be complications with anything. You and I both know that if we don't act and do this surgery, our days are numbered. I am 42yo and I feel that my luck will run out soon if I don't make the change. Just stay positive and think about all the good things that will come out of the surgery. For me, it is playing with my kids, going on rides with them and just being here for a long time with my wife and kids and someday grandkids. Good luck and keep your head up!!!!
