Ive been on amitriptyline now for 3 weeks (started at 10mg now at 20mg) I havent had any side effect, it doesnt even make me sleepy. It helps me a lot with pain and calms my anxiety and emotional spikes a lot even at this low dose. I'm surprised, even though its not an SSRI but still an antidepressant, in the past any SSRI id taken really didnt go over well.
