Don't worry about the endoscopy. It's important for them to have so they know what's in your stomach and aren't suprised by anything they find in there. They are also checking for polyps or ulcers. You'll need somoene to go with you to bring you home, but I went to work after mine. No big deal. They put you to sleep, you take a little nap, and you wake up. That's all! I'm also doing 6 months of nutrition. Waiting is the hardest part. It took me decades to gain the weight so waiting 6 months for the surgery to get it off is okay. At least that's what I tell myself when I'm being positive about it.
