I had an attack of pancreatitis about three years ago that dumped me in hospital for a couple of days, nil by mouth drip job. I recovered completely within hours, but the doc told me that my blood amylase had been sky-high but that there was no discernible bile duct blockage or anything. I returned to cautious boozing a few weeks later (the docs didn't ban me!) and I've had no trouble since. Never say never...
