I took my first dose of amitriptiline (generic for Elavil) last night and will take my second tonight, but I'm not sure what to expect. My doctor wants me to take 10 mg at bedtime to help with pain and to help me sleep. I don't think it made any difference last night, but I'm not sure. How long does it take to see a result from taking low doses of Elavil? --Laura R.M.
