Elavil
"I was previously on Cymbalta, 60mg daily, for migraine prevention.  I liked it and had minimal side effects.  I lost my job and am now only on Tricare so the doctor put me on Elavil, 10mg.  He told me to increase the dose by 10mg every four days.  I was drowsy on 10mg and a little less drowsy at 20mg.  As soon as I increased to 30mg I couldn't sleep and felt shakey during the day. I tried it for four nights and, after about 4 or less hours of sleep each night, I reduced the dose to 20mg.  I noticed my neck pain decreased at the 30mg but I can't function without any sleep.  I have had two migraines while on the 10 and 20mg doses of this medication.  SSRIs usually make me hyper and get insomnia so I wasn't surprised."
