If you're quitting the clonazepam for good I'd finish that before thinking about the second drug. When you have successfully stopped the clonazepam and evaluated how you feel at that time, when you know any withdrawal problems are resolved, then you should talk to your psychiatrist about the second one. You don't want to be going through stoppage effects if any occur with two drugs at the same time. The general schedule for stopping any of these meds is to taper off as slowly as you need to, not a set schedule set for everyone. We're different in how easy or hard it is. Best of luck.
Sorry the beginning got cut off
It said
I am on medication I don’t feel I need anymore and the negative side effects outweigh any benefits. I no longer have panic attacks but
I am on 50 mg of quetiapine at night...
