I have read that Klonopin when taking over a certian mg can have depressing effects. I really don't remember the site I was on when I read it but try and google Klonopin and Depression and see what you find. I hope this helps a little.
I take clonazpeam 6mg daily. It makes me feel lousy. It does relieve panic, and anxiety, but then later depression comes. It must depress some region of the brain that other tranquilizers dont like Xanax.
Does anyone else expereince this?
