Like you, I started realizing around 23 that something was wrong. I mainly ignored it because I still recovered and I could still function the next day even though I was making bad choices.
I'm 28 now and got the first taste of what real alcohol withdrawal feels like. The body can only take so much.
We are still so young. I look back and wish I could have stopped at 24! I really don't want to look back at 40, with major health problems, wishing I could have stopped at 28.
Do yourself a favor and get this crap out of your life. It's not doing you any favors
