Hi Sushee
I completely understand that you feel this is something that you need to do. In the Bear's case, we looked at this procedure and decided it wasn't for him. What he's doing now is working for him and for us. He is extremely healthy and doesn't have a family background of heart disease or diabetes to be concerned about. He had to see a cardiologist to get his pilot's licence (purely on the basis of his weight) and the cardiologist couldn't believe how strong his heart was and wanted to show his ECGs to students!
In your case you have done a lot of research and satisfied yourself this is for you. What I get worried about is people who see this as a quick fix, a magic bullet like you said before and are tempted to rush into it without looking at all the consequences, especially people who don't have any existing health problems other than being a bit overweight. Our society is obsessed with weight and IMO promotes a body shape which is unhealthy for probably 90% of the female population at least. Health is more important than being skinny but our society does not see it that way and for some people that pressure can be hard to resist when they don't fit the image.
I wish you all the best with it and I hope you will let us know how it goes for you.
