"i couldn&#039;t stay asleep, tried lunesta and ambien, they had side effects i couldn&#039;t tolerate.  sleep center said i had mild apnea and said their monitors showed me sleeping but i felt like i was awake more than they said i was and was literally exhausted every day, felt like i was on the verge of &quot;losing it,&quot; crying a lot.  was not sad/depressed--was sleep deprived.  have been taking 2 silenor a night for 2 years:  sleep like a baby, 8 hours required, wake up rested, functioning beautifully--i have my life back."
