My mother was really against me getting the surgery, she knows someone who's had some problems with malnutrition and passing out and things like that. I let her talk me out of it one time, it took me about another year and a half before I decided that I was absolutely getting the procedure done. They are improving the procedure all the time, it's probably safer to do now than it ever has been due to improvements in technique and knowledge. In the end you just have to decide that you are going to do it for you, yes family members opinions can be important but it's your life and your health. I'm not far along in the process myself, I just had my surgery on Jan 4 but prior I had severely bad acid reflux and so far I had a little heartburn today but that is the first time which is huge improvement. I can't speak to your heart problems but you said you discussed it with your doctor, did they alleviate your concerns some? Best of luck in whatever you decide.
