any problems with alprazolam withdrawal after taking more than prescribed

I was just wondering. I went through a disturbing, shocking experience and for about 3 days I took more of my alprazolam than prescribed. I went back to my usual dosage and I am having like withdrawal symptoms. Feeling numb, unable to concentrate, self-detached, unreality, feeling unable to accomplish tasks that I didn't even have to think about before. Is this normal and how long does it take to get to feeling normal again after going back to the normal dosage? Any information would be helpful.

Thank u,
