Nortriptyline
"Went to rheumatologist for fibromyalgia symptoms and he prescribed Pamelor to help me sleep.  ?  He prescribed nothing for pain as he told me my fibromyalgia was very mild.  I think the doctor was a quack!   I took it twice and both nights I was up all night and completely zonked in the morning.  Only 10mgs and this stuff made me foggier than fibro fog. It was horrible. Do not recommend."
