Very simply, how long before bed do vape or smoke up?

I’d been successfully treating my insomnia with flower for 2 years but recently when I’ve used it I either haven’t been able to get to sleep or stay asleep for more than a few hours. Normally I’d vape an hour or 45 mins before bed and that would knock me out. Now I find that my mind starts racing around the hour mark.

Mainly wondering how many people use it and then hop straight into bed.

I’ve tried swapping strains, tolerance breaks of a few weeks, and even zopiclone isn’t all that effective right now on the nights I don’t vape.
