I have a friend whose husband had terrible pancreatitis. He ended up having some kind of surgery for it.
He was a beer drinker, though, and he didn't want to stop drinking beer to help his pancreas heal. He finally did stop when he had to go on temporary tube feedings because he just couldn't digest his food normally. He was in excruciating pain a great deal of the time. It was very difficult for everyone.
Finally, he had surgery and it was deemed a success, and he recovered very well. But his doctor told him he had to cut his drinking to a minimum if he wanted to stay healthy.
