I does get better with time..but maybe not my time lol
I thought there'd be an instant glorious change when I quit - and there was a sense of relief - but it took me 3 months to start to feel really 'ok' again and a few more months to get my energy back.
At the time I figured this was the best it got, its the price I paid for leaving recovery so late...but it got a lot better.
I improved week by week, month by month year by year until about Year 5.
I think I'm back at optimum performance now.
We have to remember a lot of us drank for a long time - I was a twenty year drinker - 2 months or 3 months is great but it's a drop in the bucket compared to our drinking time.
Try and be patient.
People have no reason to lie to you when they say it gets better. It really does
