"i&#039;m a poster child for this drug. i had severe insomnia in my early 30s (i.e., no sleep for three nights running without a sleeping aid), and various rxs were of little help. i started out on 150 mg. and in the early part of the many years i&#039;ve been taking it i whittled it down to 12.5 mg, a quarter of a 50 mg pill. a ridiculously small amount, but i&#039;ve tested it and know it&#039;s not a placebo. it works perfectly for me%u2014i&#039;m drowsy within 10 minutes of taking, sleep through the night, and i&#039;m never fuzzy in the morning. highly recommend."
