Hi there; Jakemje. I think panic is right. I'm also trying (struggling) to wean/taper off of clonazepam; I've done well to cut back from x3 a day to .5 in the afternoon (my anxiety isn't too bad when I wake up), but builds in the afternoon. I usually take 1MG around 5PM because without it, I'm a basket case for some reason. So, I know its hard, but I *do* think its not helping my situation in the long-term. I admit - I'm addicted to it, and and I've struggled with addiction and alcoholism nearly all my life anyway, so I'm not shocked.
Good luck with mirtazapine and hope you feel better soon
