Not the same guy but, when I took them it was as I was laying down to try to sleep, so maybe 10 minutes before I was actually asleep.

In my experience you don't want to take them and not try to go to sleep right afterwards or you can ruin the effect, and trying to take more trying to sleep afterwards merely results in addiction and needing it to sleep at all.

I can also confirm you want a very low dosage. Higher dosages didn't help at all, just merely built tolerance to it. The ones I got were 3-5mg and I broke them up into tiny little pieces and took partial mgs at most. You want to nudge yourself towards sleep with it, not try to drug yourself with it.
