I got some thc oil with cbn in it as well for sleep. I’ve been taking a full draw of the syringe and I sit there and wait for it to kick in and it does almost nothing. So I doubled it up last night and still nothing. I do it on an empty stomach so that it goes into my system faster. But I’ve also read that doing it with food works better. Not sure what to think.
i hold it under my tongue as long as i can. it makes me salivate, though, so i always wind up swallowing after 5 min or so. also, i have a high tolerance so i take a much larger dose than you describe (not advocating that, just sayin’). one thing i’ve found is that the difference between not enough and too much is pretty small, so increase your dose with caution. it can be a pretty anxious hour when i take too much.
