I binged drinked most of my 20's and have drank a lot of wine in my 30's.
I too get floating stools but know mine is due to my pancreas seeing as my labs are elevated. However, I know that floating stools can be due to fat so if you ate a good amount of fat the day before that may be why.
The endoscope should provide you with more answers. I had a regular one two yrs ago when my gerd started and I did it wide awake, it was a breeze!
Thanks for the well wishes. Anxious and looking forward to it at the same time --if it is clear I can move on as my dr says from "doubtful cancer" to "def. not cancer", and perhaps look for other reasons as to why my pancreas is inflammed. I also think maybe lupus as I have had joint, nerve pains and twitching for a yr now-though labs for that have been clear.
