Advice on withdrawal effects of Alprazolam use? When will it end?

I was prescribed Alprazolam anti-anxiety medicine and i (ab)used it for nearly two years averaging 2mg/day.

I have been off it for nearly 4 months now, with an exception of using it twice in between while attending an important social event.

Currently my mind feels foggy, unable to concentrate entirely and feels like my short term memory is not as good as it was.

I am in my late 20’s and i have no other mental issues.

Any idea on how these withdrawal symptoms can be completely eradicated? Any other tips?

Thank you for your time!
