je3625,
AL works on other reward pathways as well as dopamine - eg GABA - so Nal doesn't remove *all* the pleasure from drinking, just some of it. you'll still get some of the AL effects - relaxation, etc. - but the Nal should take away some of the buzz/high, although as you've seen, it's a rather more subtle effect that we might have expected/wanted
you're only in your second week of what is likely to be at least a 3-6 month process, so don't be disheartened. it seems to be generally thought that if you see a honeymoon period - which you have done - then the Nal is working for you & there's a good chance TSM will work for you, but it's not going to happen overnight. as newlife says, it's taken a long time for you to get to where you are now, & it's not going to get undone in a couple of weeks
hang in there - Nal + Drinking + PATIENCE = Cure

all the best
