Hey John, welcome.
I think folks here - especially in the US - underestimate their 'units' and therefore may appear to be lighter drinkers. Before Nal I was averaging 8-10 drinks per night .. drinks, as in a 12 oz beer, or 1.5 oz 80 proof vodka, etc. So your 6-7 beers a day seems a little light

Doesn't really matter. Some drink less some more. You know you drink too much, it's always been an issue to some degree, but you are functional and care about your health. Enough to find Nal and TSM. Same here. Since Nal, and it's only been a few weeks, I have gone from ~60 drinks per weeks to fewer than 20. It is hard to have more than 2 a day. I expect to be sub-10 per week soon. It has taken zero will power, no higher power (nothing against that though), and it feels totally "normal" in a very odd way, which is not a term I thought I would ever use to describe my drinking. Good luck amigo.
