Making him go to sleep

LO (4) never gets enough sleep at night. No matter what I do he will not fall asleep before 11. It doesn't matter what time I put him to bed. Reading stories. Bath time. Lights on or off. He will talk to himself or scream in pitch black/light for hours.

Waking him up for school in the morning is a nightmare
I honestly think its heightening my anxiety. I have never wanted anxiety meds more than I do right now.

Wtf can I do?

A lot of moms say using melatonin works wonders, I've never tried it with my children but I know it works for me and DH very well.

Melatonin for sure. Ceili started at 1mg and it was too much she sat at the table staring at her fingers. She's only on 1/4mg right now and she's asleep within the hour. It's a synthetic hormone and you can buy it OTC and is like $8 a bottle.
