I've done so many things I regret while blacked out drunk which was a huge problem for me back in my active drinking days. When I would start to drink I could not control my usage at all. I also 'liked' to drink huge amounts in a short period of time which lead me to being more prone to blackouts than most people. It would lead to countless incidents of me acting like a complete moron.
As bad as that was I have used those incidents as a catalyst for how hard I work to stop my addiction. I would suggest you do the same. Do whatever you can to make sure what happened never happens again and don't ever forget what alcohol did to you that night!
