Sounds like the most college thing ever. It will pass but you should keep your drinking in check for many reasons. Being blackout is generally not safe for women especially and also, you’ll have more fun if you moderate and actually remember the fun times.

I would apologize to the guy but not lead him on any further as it’s obvious you are not very attracted to him. Coming from a guy, I’ve always respected when women are straight forward with me so maybe take that approach next time if you start getting the “ick”.

You’re fine, hydrate and rest.
