Help.

I was banded on Thursday evening 6/21. The next day I had a swallow test/xray and it showed everything in place fine. The next day I had an endoscopy, showed everything okay. But I have to sleep sitting straight up, because otherwise (and even then) I have a tickle, that causes me to cough, that hurts, and then I eventually spit up flem. I lay at night gurgling in my throat. I'm exhausted. It hurts to drink anything besides water. Chicken broth tasted great last night, but it all came back up. Had my first blended shake with protein powder, water and yogurt.
