insomnia
"I usually work a 10 hr shift in the afternoon but my boss has changed my Saturday shift to 5am-1pm. We live on a farm and have 3 outside dogs that like to bark at night.  The first morning shift I only got 2 hrs sleep because of our dogs. I purchased Zzquill to get some help falling asleep the night before my morning shifts. I took the recommended dose (2pills) at 8pm. I went to bed at 8:30. I didn't feel any effect from the medication until almost 10:30!! And then I woke up again at 12:30am! I do not recommend Zzquill if you want to fall asleep quickly and stay asleep."
