I've now taken both Melatonin and Ambien (not together!) to help me sleep. All I can say is no more dreams. For real. I can't remember any of my dreams anymore. Is this good or bad? I haven't decided.
Also, waking up in the morning after taking one of these aides isn't easy. I used to hear my alarm and jump out of bed, no snoozing. Now I'm a snooze queen and that's definitely not a good thing.
