"i, a 21 yeard old male, was prescribed 10 mg ambien a few weeks ago for insomnia. i&#039;ve dealt with insomnia for several years, i&#039;d lie in bed with my eyes closed for 10 hours and would often not sleep for a second. or if i did, it was for an hour or 2 and i rarely felt rested. beforehand, i tried many sleeping aids (melatonin, belsomra, trazadone) and nothing worked. within 20 minutes of taking ambien for the first time i was out like a light and slept 8+ hours for the first time in years. however, i&#039;ve been more recently experiencing the problem of not only waking up feeling groggy, but feeling that throughout the day. even 8+ hours and a significant amount of caffeine later, i feel far less attentive than i was when i was sleep deprived."
