The results of my endoscopy are good but slightly frustrating. He found no stricture and no ulcers, but the opening if my stoma (where my esophogaus meets my stomach) was only 11mm, he widened it to 18mm which is about as wide as they will go. After my endoscopy I ate lunch and was able to get down a more normal portion (normal for a person six months out from gastric bypass). I've been drinking all day without a problem, but this evening the slight discomfort is back and though I was able to eat more than I have in the past month for dinner, I still could not get down as much food as I had in the past.
I'm going to give it a few days and take it easy on my pouch. If that doesn't fix it I'll be back to the doctor to figure out what the next steps are. I did get some cool pictures of my insides that I'll post when I get them scanned.
