insomnia
"For when my mind won't shut off at night, no matter how tired I am, I have my lorazepam. I cut them in half so they last me longer. I tend to take them after 2-3 days of not sleeping and they work great. You don't feel anything, no sleepiness, grogginess, or tiredness. Just take it an hour before bedtime and you can continue to watch TV or do whatever, knowing that half an hour after you hit the pillow you'll be bored into sleep."
