I was positive I didn't want to quit. Even when I was at the point where I felt miserable drinking and even more miserable not drinking, I still didn't want to quit. I knew I needed to, but I sure didn't want to.
Now, over five months sober, I'm positive that I never want to drink again. To ever go back to that life is horrifying to even think about.
Time can change a lot about a person's thought process. Why not go a few months sober and then reflect back on this post? I bet your mind will change. I know mine did with a little sobriety under my belt, and I'd bet others would attest to the same.
Doing this for your young kids isn't a bad contributing factor to get sober at all. I have kids of my own ranging from almost adult to less than a year. Of course I wanted to do this for them. But that never would have sustained me. I needed to do it for myself. For my health, finances, sanity, etc.
Please do this for yourself, first and foremost. You're worth it!
