I was prescribed Amitriptyline 10mg to be taken at nighttime for migraine prevention. Well it was giving making my already bad insomnia even worse to the point that I was unable to sleep even with my prescription medicine for sleep. So I stopped taking it. I had only been taking it for a week and at such a low dose I thought it would be fine. Well now after 2 days I began experience unremitting dizziness I have been dizzy for two days and I started taking the Amitriptyline at 5mg hoping it would go away. Anyone experience dizzy from stopping Amitriptyline and if so how long did this last?
