Blacking out

Hey guys, last year I entered college and I have being blacking out often I have been drinking since the age of 15 and I know the point where I need to stop but when this happens I don’t even feel it coming or when it’s coming, I am getting kinda worried, because I can’t enjoy a night out, to the point of being kicked out of club and not remembering any of it and I can’t control myself , it’s a shame. Any tips to avoid this?
