Im sorry to hear about your pancreas.
It sounds like that you had Acute pancreatitis in the past which is essentially and inflammation of the pancreas. This causes the pancreas to start digesting itself due to the release of enzymes. Now Alcohol is the number one cause of this problem and since you seemed to have had this episode in the past, it would be advisable that you NOT drink any alcohol and even if you do drink alcohol, drinking large amounts like you would on a party can aggravate the situation and cause you to develop another attack. Acute pancreatitis is VERY dangerous and can lead to respiratory failure, renal failure and in severe cases, death. No party is worth that risk.
Secondly, even if you didnt have acute pancreatitis, you could currently have chronic pancreatitis which as the name states is a chronic inflammation and this again can cause severe digestive issues and be changed into acute pancreatitis because of the alcohol.
So in short, NO you shouldnt be drinking alcohol with your pancreas. You can always have fun apart from drinking on the cruise.
