"i&#039;m 19 and have been taking this medicine for insomnia since i was 8 or 9 years old (it&#039;s been so long that i can&#039;t recall exactly when i started). it is the only thing that can put me to sleep as my insomnia is so bad that if i don&#039;t take amitriptyline, i will be up for days. the only issue is that it does make me very groggy in the morning, but that could just be due to the fact that i am a teenager."
