Another question i have is does alcohol abuse make you dumber?
Alcohol will definitely affect your thinking and memory. If you stop early enough, though, your brain can recover from a lot of the damage. I definitely saw a change after I got sober.
I also found that my anxiety and depression lifted once I stopped drinking. I became a calmer, more positive person.
You took a major step today by reaching out and admitting you have a problem. That's awesome! None of us can get/stay sober on our own. Until I came here, I couldn't make it through a day without caving.
The support here is great - Stick around and keep reading.
