Try to relax, you'll do great. Just focus on where you are going. As far as complications to, All I have to say about that is there are a lot more complications form being obese. I am a living testimony to that. My lungs are my and my doc biggest concern as I have damage from asthma and pneumonia. I also have murrmers from Phen Fen and that did more damage to my lungs. My arthritis is killing me. I can't walk anymore. You are young, so you want to get it done now before comorbidities get bad. You are chosing the safer path. I hope that will help you relax a little. Have a good time at your BBQ and keep busy. I'll be watching for reports about you. Diana
