When is your appointment?
The pancreas is one important organ, not only for digestion but also for producing insulin and keeping our blood sugar levels stable. They will probably want to do new tests...be honest with them about your drinking history and that round of tests three years ago, yes?
Knowing for sure what's up is easier than what-ifing and mentally churning about the possibilities, and I say this as a world-class churner.
Sending you a hug.
