How to get to sleep after an evening workout?

My schedule currently only allows me time to workout after 5 PM due to life commitments and work.

I choose to go to workout classes because I make friends, and it pushes me much harder than I would push myself, and I see benefit in those things.

That said, last night like most nights I do this I couldnt fall asleep until the sun came up, despite going to bed at 11 PM.

I'm kind of running out of ideas so I figure I'll ask here, if only because we all tend to be weird in the same ways on this forum.

I have tried everything:

* Chamomile tea

* No screens in the bedroom

* Snack before bed (this helps probably the most if not inconsistently)

* Meditation before bed

* Stretching

* Melatonin 30 minutes before desired bed time (this one also helps maybe 40% of the time)

* THC (get very stuck in my head, does not work at all)

* No/dim lights in house to trigger sleep hormone production

* Progressive relaxation

* Warm shower before bed (wakes me up)

* Cold shower before bed (WAKES me up inside)

* No caffeine after noon

* No caffeine at all (Makes me a terrible person to others)

I'm out of ideas. I'm literally giving myself insomnia with these workouts. Its almost like I cant gear down, and want to keep being productive and am running on some kind of adrenaline / cortisol diesel mix that I cant get out of my system.

Has anyone found anything that works for them?
