I have been taking amitriptyline since January and I agree with Farmergirl, it is very sedating. I was on 200mg for most of the time since January but am starting to reduce it now - it really knocks you out. To begin with I struggled to wake up in the morning but as long as I take it early enough in the evening I'm fine now. When I first started I was also given zopiclone and I really couldn't stay awake the next day.
