"i have been taking ambien for about 3 years. i have anxiety disorder and have had trouble getting to sleep as long as i remember. i worked night shifts because it was easier. after i had kids, i had to become a day person! i had terrible nights of falling asleep at 3-4 am after tossing and turning. i used benadryl for several years and one night it turned on me, i had anxiety attacks, muscle spasm &amp; ridgidity. my doctor gave me lexapro, because i had depression at that time as well. i hated it and how numb i always felt. then he prescribed ambien. i cut the pill in half. it doesnt knock me out, it just turns my brain to slow and sleepy. i sleep like a baby. i wake very happy and alert. no more depression either."
