I am very nervous as well. I thought I was pretty set on getting the sleeve, but after talking to some of my friends about it, I seem to be way more nervous and anxious about the whole thing than I was before I spoke to them. I know they were coming from a good place and are concerned for me, but now I'm just a bit more freaked out than I was before. I am still going to get it done though, because they don't know all my health concerns if I don't get it done. Today I had my first appointment with a cardiologist to get clearance. He took an EKG and everything looked fine. He still thought that I should get a stress test done and a sonogram of my heart so that my insurance company will get off my back about it all. I would love to hear other people's stories and complaints!!
