insomnia
"I don't have trouble falling asleep, but if I happen to wake up between the hours of 2:00 am and 4:00 am, for some reason I have a hard time falling back asleep. I give myself about 10 minutes, and if I am still awake I take one capsule. Seems like it works within 15 minutes and there is ZERO morning grogginess. It is a short acting medication so it really isn't designed to be taken right when you go to bed. Sometimes I will take a Sonata and then check my email while waiting for it to work----big mistake, as I write some very loopy, misspelled things which I have only the vaguest memory of doing. "
