"i took ambien awhile back for insomnia. within 20 minutes i was out. woke up refreshed after 6 - 8 hours. caution: for me, it was addicting and i could not sleep without it. also for me, i would not remember activities i may or may not have done the night before. unplug your phone, you may regret who you call and the conversation you had. i cannot take ambien for those reasons, but it did work for getting to sleep!"
