Works Great – No Grogginess!
ZzzQuil ULTRA is my go-to for occasional sleepless nights. It helps me fall asleep fast and stay asleep without feeling groggy the next day. The 25mg of doxylamine is strong but not overwhelming, and the 48-tablet pack is a great value. Just be sure to take it when you can get a full night’s rest. Highly recommended!

Only works so-so.
I’ve been trying this for a full week now and it’s only been effective about half the time and always takes at least an hour to kick in, even if I’m already lying in bed. After waking up again, I felt washed out and foggy. I’ve tried Unisom and this was slightly better at helping me get to sleep, but made me feel worse the next day.
Steven Whiting –

Severe anxiety reaction, not good!
I will relay my experience to save others from the same trouble.I have had a hard time getting enough sleep for several years. Ive tried a wide variety of products but nothing worked well. I decided to try this product due to the trusted Nyquil brand name.I used these pills over the course of 6 months daily and only had slightly increased sleep hours. I used as directed, did not do higher doses. The small improvement was ok, better than no improvement at all so I stayed on it.At the same time I began to have severe anxiety especially at night and felt depressed. I chalked this up due to general life stress. However, generally I am not a person who is depressed.Fast forward, despite nothing outwardly being wrong I became so depressed I began to try to isolate any cause. After trying a number of pills and supplements, I finally cut out these pills.Within 2 days I felt like my old self. The anxiety lowered to a moderate level I would associate with any normal stressful life situation. I stopped having night terrors. I felt optimisitic and could once again handle life’s issues with logic and strategy.It was obvious these pills were the problem.I don’t know if these pills caused a bad reaction due to other medication or herbs. But this experience was a literal nightmare for me and I suggest proceeding with caution. After being off of these pills for approx 1.5 months it’s clear that was the problem.I have never had trouble with any other Nyquil item such as cold medicine day or night, or sleep aids.
