Let's just hope he feels the same way because if he want's to drink he is going to.
There is no predicting if he will have withdrawals or what will happen when he doesn't drink; however, its very possible. The doctors should know about his alcohol intake if he is being sedated or whatever, can be affected by his alcohol consumption.
If you are going to go the route of letting his doctors know I wouldn't sugar coat it.
