Yeah I actually had a similar experience the other night, I was on 3-MeO, more than usual because I wanted to feel some dissociation, and I drank the amount I usually would while hanging out with or without microdosing 3-MeO. I ended up laid out on the floor for a while because when I wasn't laying down I was nauseous and spinning, very obviously quite intoxicated. My friends commented on it the next day, oh man Xorkoth, you were fucked up last night. Yep, I was. I still pulled it together to play some music later in the night but it reminded me that alcohol can be a nasty bitch sometimes.
But hey, it got me thinking I should be drinking less, and so I haven't since then. I probably will tomorrow night because I'm going to see String Cheese and party all night. Alcohol can be good but moderation is also good. I had slipped into a tendency to always drink on dissociatives but I really do prefer not drinking on 3-MeO-PCP a lot of the time, it's a much clearer and nicer state, so smooth and lovely feeling. The alcohol turns it into a sloppy thing.
