All meds initially take time to work so your brain is trying to go back to function with out the chemicals..

I once quit Lithium and it literally took about 3 months for my brain to work and my explosive episodes to go away.

Im sure it depends what meds your on and what they are.. Are you going off more than one med at a time? If so maybe take it slower and go one at a time..

Hope things settle down quickly for you.
