How is it as a pain med? I'm currently on pregabalin which is working great but my insurance will only cover it if I try and fail amitriptyline. Since it's an antidepressant I aldo have to go off my mirtazipine which is working great other than the appetite and the hypomania (I'm bipolar). I am also on a sleeling pill so I can deal with the hypomanic insomnia.
