For Insomnia "I only took ZzzQuil for two nights. Both nights I slept just a few hours and woke up with a bad headache two mornings in a row that Advil didn't help, and it usually always does. I also noticed yesterday when watching a football game that my vision was acting weird, blurring like. I DO NOT recommend this to anyone. I have tried many over-the-counter meds, and nothing really works - does nothing at all for me, but this stuff made me miserable."

For Insomnia "I was using the liquid form, and it was fine, working for me, but yesterday I took 2 of these pills. I slept for 5 hours, and now I have a terrible headache. I took 2 painkillers, but it doesn't help at all. I can't sit or work or concentrate. Terrible pill, will not take it again."

For Insomnia "I personally wouldn’t recommend this to my worst enemy. I woke up roughly three hours after putting my head on the pillow with the absolute worst headache and stomachache I’ve ever experienced in my entire life. I’m not trying to bash this product, only sharing my personal experience. It might work for others, just not me."

For Insomnia "Tastes funny. Gave me a headache and restless legs, as well as twitching. Doesn’t help me doze off any better than not taking it."
