I think, ask your physician. I'm inclined to agree that if you still like the taste and it makes you feel good, then some indulgence won't harm you. Just be careful about alcohol and how it combines with any other drugs (like painkillers) you are taking. Pharmicists can give good advice about that too.
Go well with your treatment. I start mine of radiotherapy and four days of chemo, this thursday. I'll visit the forums when I can to see how you are going.
cheers
