Thanks for your replies.

I think I might have found myself in a similar place. The Nal side effects are really off putting, so I tend to not bother drinking at all. Like you, I tried drinking without Nal, but with different results. I did not like the taste of beer, and ended up only having two of them. I then tried to have beer with Nal, and found that I preferred the taste of beer with Nal, but that I still didn't really want to drink that much.
It actually makes me feel a little bit sick to think of the taste of beer now.
