The only way I really made an early wake up work was wearing amber safety glasses to block blue light for an hour or two before bed every night.

I will note that if you feel absolutely terrible on 8-9 hours of sleep, you should check with a doctor about it. I have hypothyroidism and was on too low a dose of medication, and felt so tired after work that I almost drove on the wrong side of the road. I'd thought this was simply from moving my sleep schedule and getting less sleep after starting a new job, but I got a blood test for unrelated reasons and found I was hypothyroid. A couple weeks after starting the new dose of medication and I feel like a new person.
