I'm sorry you got to this point but drinking isn't a solution.
I quit drinking without any medicines. I don't have any family, and only a couple friends at that time. I mean, you have to create friendships and meaning.
I went from drinking 12-20 ounces of hard liquor every day down to two ounces the next day. One ounce on day two and a half-shot on day three. In the interest of full disclosure I didn't know that *could* be dangerous, but that's how I quit and I was okay. It wasn't easy and I was a hot mess for a couple weeks, but - I haven't had a drink in over 4 years.
How about rehab? If you can't do it on your own, help is out there.
