Amitriptyline
"I was given 10mg Amitriptyline for insomnia, anxiety and migraines.  It didn't seem to help the insomnia much, even with taking .25mg - .5mg Klonopin.   So the doctor gave me 25mg Amitriptyline which I just couldn't tolerate.  Gave me worse insomnia, nightmares, even some bruises and muscle spasms in my back, which I'm assuming is related to the medication.   I'm going to go back down to the 10mg and see what happens.  I'm so sad because I've been reading all of these great reviews, and was really hoping it would help.  I'm underweight, and just very sensitive to most medicines.  So I would say give it a try, since it works differently for everyone.  I will update soon."
