How to stop blackouts

Recently I keep getting blackout drunk. This used to happen when I was younger but then has started to occur again and I really hate it. It’s so embarrassing and I feel like I’ve gone off the rails and being very risky in my behaviour. I hate being such a liability and was wondering if there is anything I can do to stop it? Is becoming sober the only way? As I never know when the turning point is. I’ve tried drinking water, not mixing. Has anyone had any luck with stopping blackouts at all?
