Robert ★★★★★

The 3 mg dose is just right for me—not too strong, not too weak. I've been taking it about 30 minutes before bed and I'm out within the hour, and I actually stay asleep through the night now.

Stella U. ★★★★★

Falling asleep used to take me over an hour of tossing and turning, but since taking one of these about 30 minutes before bed, I'm out within minutes. I've been sleeping through the whole night without that groggy feeling the next morning.

Kevin E. ★★★★★

I usually wake up multiple times during the night, but since taking one of these about 30 minutes before bed I've been sleeping straight through until my alarm. The tablets are small and easy to swallow, which is a nice bonus.
