I'm nervous too ! Actually very nervous about the things you mentioned, esp. having this thing on my stomach forever. I've talked to doctors and patients and you have to accept this fact - it's not a short term solution. I'm not quite there yet. But, what has made the most sense to me is looking back at my own history - I've been on a million diets for the past 25 years, with no lasting success; as with many people, I'm much heavier now than when I started. If it takes a "forever" tool to get me healthy, I may have to accept a "forever" approach. I also think the thing to do is to talk to your doctor or her/his office for some reassurance and information. Good luck - and I think some nervousness is very very natural, but be sure you're really ready. This is for you !!
