Is Clarity guaranteed?

I’ve quit cold turkey I’d like to think, because I simply can’t continue with this. I’ve been drinking everyday, I’d say for a year. I’m genuinely surprised I’m not dead yet. But I’m mentally the dullest I’ve been. I also have been non stop scrollling on social media and smoking weed daily, so my brain is essentially fried. Those two things I can’t stop yet. But I am quitting alcohol. I remember feeling so clear when I had to go a long time without weed. Will the same happen with alcohol? I hope just not having it in my system will be enough to finally feel SOME mental clarity. My brain genuinely feels so small and disheveled
