My last pill of amitriptyline 10mg was sunday night. it's friday night and i'm beginning to have nausea. no sxs of withdrawal until now. related? how long will withdrawal sxs last?

Doubtful: I would've believed nausea as a symptom with nortriptyline more if you would've told that you had just increased the dose....not coming off. I don't advocate cold turkey'ing nortriptyline but 10 mg. is such a piddly dose that I can't imagine causing GI symptoms after stopping it 1 week ago. Nope, I vote for NOT RELATED. Look for other cause by consulting your physician.

Most likely not: likely not related. you were on a small dose, and so long after you stopped that it is likely not related.
