Thank you for all the replies. It really does help hearing other people's experiences. Nortriptyline is the only medication I'm on and when I called my neurologist this past week with my question about the melatonin, his receptionist got back with me with the answer. So I didn't talk to my doctor myself, but the receptionist said that he said it would be okay to mix the two. He did not however suggest a particular dose of melatonin.

I've always been hesistant to use medication, and I think that's part of the reason I'm concerned about mixing the two. Glad to hear others here have done it successfully. I may try and go to the store tonight and find the lowest dose possible - or maybe I could split a tablet if I can't find a small dose. I am just desperate for some uninterrupted sleep! Thank you again!
