This works really nicely. I have trouble sleeping and staying asleep. I used to take benadryl nightly until I learned that there is a link to regular use increasing risks of dementia. I quit cold turkey and immediately went back to having trouble sleeping. It didn't matter how tired I was, I could not sleep through the night and it would take 1-3 hours to get back to sleep. Desperate, I tried this. I started out by taking one pill about an hour before bed, and a second pill right before bed. This helped me get sleepy, and the second dose helped me stay asleep all night. I just take 2 at once now because I'm bad at timing a bed time. Both ways worked great though. I use this in combination of using a very strong blue light filter on my phone while I read before bed
