Heartburn & Upper GI Endoscopy

Hi everyone! I am 25 years old. I had my surgery 13 months ago. I've lost 80 lbs so far. I try to follow all of the rules and be a good bandster. But lately, I have had bad heartburn. I haven't been able to keep anything down since it started a couple days ago. I went to the doctor and he scheduled an upper GI endoscopy this Friday. Has anyone else had any problems with heartburn with their band? Has anyone ever had an upper endoscopy? I'm supposed to be sedated, so I guess it should be too bad. I know a lot of this is stress. I'm a teacher, and my district is cutting jobs, so I'm worried about that. Plus my family has been giving me a lot of problems about my boyfriend lately. It's just all so much. To make it worse, my lapband doctor's machine is down, so he can't unfill me at all. I'm basically on liquids, and I'm even having trouble keeping THEM down!
