It's commonly used to treat insomnia, though I believe it's being used less and less due to the side effects
One of the weird side effects is that if I don't go to sleep and force my self to be awake, I get these quirky weak hallucinations, like the letters on my screen are 'wobbly' individually. Static images shift in dream like manners, like they're animated. It looks completely real but I know it isn't, and doesn't particularly impair me, just gives a slight mellow chill.
I can see the recreational potential in this drug, but for insomniacs it can be a godsend to have a small "you will fall asleep in 15 minutes" kill-switch on demand when you need it.
Before taking it I had insomnia, prescribed this drug for different reasons but it helped with that: especially the wake up at 3am problem but also the get to sleep problem.
But it is mild as to not worry me I can wake up in an emergency and be lucid if needed.
