I'm 4 days post op and this was my first surgery. My biggest fear was not waking up from the anesthesia but I had decided it was a necessary risk in order to get my weight and health under control. You're definitely better off having surgery at a younger age while still healthy as opposed to having a heart attack or something else down the road. After having the procedure done, I can look back and realize I was worrying much more than I should have. All of the pre-op testing and analysis that goes on before they will even put you under goes to show that you probably won't be recommended for surgery if you are a risk. Thousands of people go under anesthesia every day and the doctors really do know what they are doing. They are in complete control of your body while you are under since you have a breathing tube and they are monitoring and controlling blood pressure, oxygen, etc. The worst part of it for me was a headache and sore throat for a day or two. The biggest thing I wasn't prepared for was the pain, nausea, and inability to eat/drink for a few days due to the sleeve. It has gotten better every day though and the lbs are coming off so I'm still glad I went through with it. Be sure your mentally prepared for the journey, its not easy at first, but It may be one of the best decisions of your life! Best of luck!
