"my doctor had prescribed ambien.  before taking it, i wanted to know side-effects.  found that it can have very negative unwanted side-effects.  therefore, did not even take one tablet.  threw them out!  so, i turned to the equate nighttime sleep aid, 50mg., which was a good choice.  help me to sleep well.  i do, though, awake although briefly around 2:30-3:00 am after having gong to bed at 9:00 pm.  notice some daytime sleepiness at times."
