Hi Patch,
As a Pancreatitis sufferer since 2004 and waiting for one third of my Pancreas to be cut off I strongly advise you to work with your GP. Believe me, Pancreatitis is an illness you really do not want to suffer from.
Having said that, my Pancreatitis was not due to alcohol and although I stopped drinking in 1974 and have been teatotal since, the Docs tried their best to put it down to alcohol. One even said that it must be a "late reaction" to my drinking days in the army, 30 years later.
