Advice: Night Owl cant do mornings

Since I was in my mid-teens I have gradually over time become Night Owl. It is typical in our teens that our biological clock/circadian rhythm nudges a few hours ahead and eventually in our adult years, merely by routine, we hardwire ourselves to getting up early. I know most ppl feel groggy and tired when they get up, some ppl take coffee throughout the morning, etc but still manage ok and are none the worst of it by the time the afternoon comes around.

Unfortunately I simply cant and end up feeling like absolute sh1t getting up early. Its as though Im at the tail end of a hangover - I get a bit shaky, I feel weird, sometimes as though Im going to pass out, on occasions I actually felt like I was going to have a heart attack. I cant concentrate, no appetite and brain function capacity is shot.

I have tried lights/devices off before 10, no coffee, relaxation, meditation, relaxing music, no late meals, herbal teas, eat first thing in the morning, etc and nothing seems to work. I spoke to my GP but was told that meds are only for temporary issues and longterm would be very much advised against. I usually fall asleep between 3 and 6 and wake up around 12 and 2. Im a great sleeper but simply cant function with less than 7 1/2 hours sleep.

Im curious if anyone else has these issues. Apparently 20% of ppl are night owls and 5% extreme night owls. Its lead me to having to do jobs in Hotel/Bar/Restaurant that allow me a late schedule. Im at the point now where this is no longer a viable option in many ways, particularly financially and socially.

Ive heard of an organization *whos name I cant remember) who want to influence jobs to be more Night Owl friendly. They've mentioned things like reduction in traffic (less rush hour), improved performance, improved health, better well-being within in the workplace.

Would be interested in others experience. Has anyone overcome being an extreme Night Owl? Maybe tried and failed?
