Blackouts and Attention

Hey boards!

So i've recently realized that I have to control my drinking. I'm such a quiet girl usually but as soon as I start drinking after 2-3 drinks I change completely.
It's like I crave attention and shift anyone who gives me the slightest bit of attention.

I also suffer from total blackouts after a certain number of drinks, I'm fine one minute then the next i'm in blackout mode. I've been told that I don't come across as overly intoxicated but I never have any recollection of what I do etc?

I usually go out 5-6 times a month and on every single night I suffer from a blackout and severe hangovers that last 2-3 days.

I'm only 20 and was wondering if anyone else my age suffers from this and if you have any tips on how to control them?

I really don't know why I become a 'slut', maybe I just feel more confident when i've a few drinks.

Any help/tips would be greatly appreciated.
