What did I do?, again

I went drink last Saturday with my friends. I thought I had a couple of glasses wine and cocktail and I was merry, but just not merry, I was wasted, crap and shit. I was asked "Were you ok the next morning?" by friends after the Saturday. It seemed I did something wrong, strange or funny as usual. I hope I just boozed....actually, I only remeber I was too friendly at the night and I chatted somebody who I had never met and I can't remember what I talked exactly.... Can't I learn something from I did before? How many times I regreted and how many times I swered I'll never do something I regret after I had drink this year? I feel sorry to people (mainly, my friends's friends) who I annoyed. I hope nobody remember about me at the night......
