"tried this after my new dr took me off of ambien that i&#039;d been on for 3 1/2 years  by a sleep dr for my insomnia, i can stay wide awake for up to 48 hours &amp; then if i do fall asleep only get between 2-6 hours of sleep. new dr thinks i&#039;m depressed but i&#039;m far from that &amp; keeps wanting to put me on depression medicine!! called sleep dr back in iowa to tell new dr here in louisiana that i have insomnia which she did but new dr doesn&#039;t believe sleep specialist!!"
