Do not EVER stop these meds “cold turkey” You must taper them off slowly, the Effexor a longer taper than the Ativan. I just quit Ativan and it took me three days before I felt OK. I was anxious, had goose bumps, couldn’t sit still, just basically sat in bed until the symptoms subsided. The SSRI’s take much longer and could be the source of your rage but stopping two is a bad idea.
