I have 8 months sober, and I feel like each month has gotten easier, and the six month mark seemed to be when things felt smoother. I have something in my head about getting to the one year mark because I will have made it through every holiday, every season sober.
I stopped obsessing about alcohol after about 3/4 months and that was also a big step.
If you are just starting out know those first few difficult days/weeks are worth getting through. Life is so much better without alcohol in it.
