I used to have terrible panic attacks when I drank, especially after a heavy period of drinking. After having been sober for some time the anxiety mostly went away, at least the worst of it... But I think that 2 months is not a very long time for your brain to recover... that's just my opinion. I do still have some anxiety though, probably because the anxiety came from me in the first place, the alcohol just made something worse that was already there a bit.
