benzodiazepine withdrawal
"I have had a shaking problem since I was eight and I had insomnia I was self medicating with Xanex but if I went one day without one it was hell, plus they would not last all night I would wake up and could not sleep. Then the doctor prescribed clonazePAM and I had no problems I had to increase my dose after a while to two mg twice daily and I never had side effects slept well and was calm it worked great for three years now"
