My serious anxiety when drinking pretty much went away entirely when I quit.
Every week better and better, and by one month I felt "normal" again.
Everyone is different, but I was shocked at how much better I felt (and how quickly) removing alcohol entirely from life.
No reason you cannot start to taper now if you are unwilling to quit entirely yet.
It will make things easier when you are ready to commit.
Life is so much better sober! Good luck!
