Yeh, blackouts can and will get progressively worse.
I had blackouts for years and it just gets more embarrassing and worse behavior as time goes on. Amazing how low I went when I drank. It's probably a blessing in a way that I don't remember a lot of it.
I wouldn't go back to that bar. No need to if you are going to stop drinking.
Are you ready to quit? Or do you want to keep making bigger and bigger mistakes? I hope you'll stick around and use this as a learning experience of what not to do.
