Is it normal to always hook up with random guys when drunk?

Me and my ex were together for years and I was always faithful to him. However, I'm at university now and we've split. It seems like every time I go out I get drunk and pull some guy and end up making out with them (at the least) or doing sexual things with them. In the last 5 months I have given three different guys oral sex and had sex with one guy. This wouldn't bother me but I only actually liked one of the guys, the other 3 I would never have gone with if I hadn't been drunk. Does this happen this often with other girls? Or is this actually not as bad as I think?

The problem for me is that I wasn't attracted to the guys, not that I think theres anything wrong with behaving like this if you are attracted to them. Also, please dont comment saying "cut down on drinking" or "quit drinking", this is something I have already considered and am working on, also I'm not an alcoholic or anything, just your average english uni student.
