Tips for not drinking so much when I go out

I’m in college, and I’ve been getting a little bit too drunk when going out and am looking for tips for avoiding that. I participate in a culture where drinking to excess is accepted and almost encouraged (think: fraternity), and while it’s fine for me to drink that much in that context, I’ve found that I’ve been getting too drunk in other contexts simply because having 12+ drinks is completely ‘normal’ around my friends. I wouldn’t consider myself an alcoholic given that I never choose to drink except when others are drinking (ie I’m never the initiator and don’t seek out opportunities to drink), but I’m wondering: does anyone have any tips for slowing down the drinking when I don’t want to get that drunk? Drinking less is the obvious answer, but I find that once I have a certain number of drinks, I tend to continue until I’ve had too much. Thanks in advance!
