larry27, you didn't ask me, but I can give my own reasons for doing this.
After a few months taking Nal, you'll realize that it really prevents your body from reacting to alcohol the way it normally used to do it. I mean, you feel no pleasure anymore, no pleasure at all. And after so many years living with that routine and the sensation alcohol used to cause, it gets really weird when that happens.
I always drank on Friday or Saturday. So during many years Friday was a very expected day by me. After Nal started working, Friday became a regular, ordinary day. And I felt that SO strange!
So, Idecided to drink without Nal on last New Years eve. I thought I would manage to do it just twice or three times, but all that Hell ended up coming back.
Anyway, now I'm here again, doing TSM. Good luck for us all.
