Happy at first, and then go on to quiet-drowsy. If I'm still awake about 4-5 hours after my last drink, I may get sullen. Anything more than 1 drink starts to reduce my sexual performance, not help it.
Funny, we were talking about this last night when we got back from the bar, because one of our good friends met us there. And he usually gets silly-giddy when drinking, laughing almost non-stop, which he did last night.
It's curious how different people react to alcohol, and sometimes the kind of alcohol seems to play a part, too. I had a BF who was very much affected by the kind, his nastiest reaction being to gin. Even he admitted it made him act "like a wounded dog."
Early in our relationship he got drunk at a house party I gave for a small group of gay men, including a gay couple who had never been to my place before. My BF took his pants off and was running around in his tighty-whities, getting argumentative with me in front of them, and telling everyone how many millions he was worth, how many homes he had, etc. He wasn't lying, but obviously totally out of line in several ways. The new couple left early.
The BF showed up the next morning looking pretty wasted (he'd refused my offer to stay over and foolishly drove home), and was the only time I saw him completely remorseful & apologetic. I think he wanted assurance that he hadn't behaved as badly as he half-remembered.
I felt obliged to tell him the truth as gently as I could, and he offered to never see me again. I declined and we stayed together another year, with him never getting that drunk again, and me always reminding him of that incident when he started overdoing it. But gin still could turn him nasty.
Other people get angry and argumentative, some even combative. I hate a sloppy drunk, really anyone who doesn't know when to stop. And if you make your drinking problem MY problem when we're out somewhere, I will be especially & personally offended, to have been embarrassed & stressed in public by your immature behavior. Trust me, you don't want that.
