Wear special orange glasses to filter out the blue light if you really struggle getting to sleep.
I use a silk sleepmask to block out all the light. I need it pitch black to be able to sleep, but DP hates it too dark in the room. So I have to use a sleepmask to get any sleep.
I must admit, a lot of the early bird types I know see to think being up early is some sort of indicator of superiority. I'm more of a night owl type, but 30 years of getting up early for work means I'm fine at getting up at 6am now (although if off work for any length of time, my wake-up and sleep times start shifting later and later; going back to work can be hard those first couple of days).
I once had a conversation with my dad about getting up. Mum had recently retired, and dad had been medically retired a few years before. It was about 9am in the morning and I had popped in to drop something off. Dad was hoovering, and started chuntering at me about how mum wasn't getting up at the crack of dawn like him, and getting stuff done. She was getting up at about 9:30 am and going to bed around 1-2am.
So, I pointed out to dad that she wasn't really getting any more sleep than him, and often pottered about getting stuff done at midnight, long after he went to bed at 10ish. I actually said to him "Dad, you and mum are both retired, and mum can get up early if she needs to. So, what does she have to get up for?"
He has never raised this subject since. I think I punctured his balloon there.
