I've done exactly what the author talks about: write long incoherent but beautifully written poetry, dive deep into studies and journals about the most random subjects, and have auditory hallucinations. But, what she doesn't talk about is the horror stories that come with it.
I've destroyed countless relationships. I've had friends that refuse to pick up any of my calls after 12am. I've crashed my car into a tree because of sleep eating. I've withdrawn from the medication, and don't sleep for 3-4 days. I've taken Ambien, then drank an entire bottle of wine, and the next morning to find out that I took 6 more Ambiens. I should be dead.
If you haven't taken Ambien in the past, and are interested, I would just avoid it at all costs.
