Insomnia
"I have been off and on Lunesta 3mg for over 10 years.

The reason I get off of it, I gain a tolerance to it, so I have to try something else so I can get Lunesta out of my system. Usually I get on Valium 10mg or stronger because nothing else works.

I can stay awake for weeks. Yes, weeks. 

My longest time staying awake, 20 days.

Lunesta works for a lot of people, I just have a high tolerance to most medications."
