I'm at over 3 months now and some days are good and some days are still hard. Some days I feel like my usual self, but then there are other days where everything feels like a struggle (thinking, expressing myself, etc.). It comes and goes though.
I never experienced nausea or anxiety though.
Keep on concentrating on moving forward. I agree with Patman that being sober and dealing with some of these issues is better than the hell I was in when drinking. I am grateful to be out of that cycle and never want to have to go through this again.
