I take 15mg every night about an hour before bedtime. Most nights it works well – keeps me asleep 6-7 hours before waking. Can sleep a few more hours if I don’t have to be out the house. The odd rare night it doesn’t work as well for some reason. Maybe too much caffeine throughout the day. Who knows. But more often than not it’s a good sleep aid. Works well for anxiety too. I rarely panic when in public places now.
