Let me tell YOU a thing or two about Ambien. When I was fourteen some quack pyschiatrist prescribed Ambien for me, and it FUCKED me up like no other. It has already been proven that dreams are a necessity for life. Experiments where test subjects were repeatedly woken soon as they lasped into REM state, and then evenutally began to suffer from ill health and psychosis have proven this. Ambien messes with the brain's natural dream processes, and from my own experience and people I've talked to who have also unfortunately been subjected to this drug, they experience extremes of either complete dreamlessness, or dreams so vivid they cannot be distinguished from reality (something that is obivously going to be very detrimental to someone having nightmares about Provo Canyon School or any lockdown teen prison.) Point is- stay away from Ambien. For insomnia, I would recommend a cup of chamomile tea, or if that doesn't work, try some valerian and maybe exercise before bed, try to get more fresh air during the day. Stick to the natural stuff.
