I have to laugh at myself when I think about this. I like wine, so wine was what I tried to moderate. I don't ever recall having a blackout with beer or any other type of alcohol, so I would switch to these types of drinks when I was trying to control my drinking.
Unfortunately (or fortunately depending on how you look at it), drinking other types of liquor just weakened my will power to switch back to wine, which is what I wanted in the first place. It is like I would use beer to "sneak" back up to my wine drinking.
I have spent years of my life wrestling with moderation, an exhausting and fruitless effort for me.
Yours are good questions. The best of luck to you.
