Insomnia hacks?

Hey people, currently struggling with insomnia. So far i have tried:

- a sleep therapist

- a set routine before going to bed

- not laying in bed during the day and only laying in bed when im about to sleep

- showering before going to bed

- yoga

- those weird hypnosis youtube vidoes

- mindfullness

- running

- p90x workouts

- eating healthier

- quiting caffeine

- melatonine (gives me migraines:( )

- covering myself in baby Zwitsal nighty night lavender lotion

- covering myself in calming natural oils (this just felt gross, sensory nightmare)

- drinking a litre of warm milk (i got diarhea)

- watching those youtube history lectures

- sleeping upside down

- sleeping with an icepack and sleeping with a hot water bottle

- weed (expensive :( and weird dreams )

- hard reset by not sleeping for a whole night, just going about my day and going to bed at a reasonable hour the next night

- those weird military breathing techniques

(oh yeah i also have a weighted blanket)

Does anybody have any other suggestions/tips/hacks to get my sleeping schedule on track again? 

At this point im starting to sort of halucinate like little insects and like fruiflies floating around my vision so i look like a crazy person just swatting air apparently sos.
