Hi, I've been on amitriptyline for neuropathic pain for two year. I am now coming off as the drug over 40mg is giving me tachycardia. So I've reduced from 40 to 25mg daily over a course of 4 weeks, in the last week I have begun not sleeping, or constantly waking up throughout the night. Was anticipating this at some point as sedation is one of its key side-effects. I want to come off it completely (I'm currently not experiencing any pain-fingers crossed), but obviously this is going to incur more insomnia? Has anybody got any advice similar experiences?
