Regardless, for me:
8:30 alarm, although I'm usually stirring by then. Meditate, coffee, email check (I rarely reply at this time).
I drink decaf coffee in the afternoon, and decaf tea in the evening (it's not as good, but cutting the bulk of my caffeine out after my breakfast cup has really helped my sleep). I try to keep some level of routine/discipline, including an hour or so to relax before bed, which is usually around 12:30-1am. I forced myself to get up 'early' for a fair while, but after reading Matthew Walker's "Why We Sleep" (https://www.amazon.co.uk/Why-We-Sleep-Science-Dreams/dp/0141...) I just accepted I was more of a night owl and adjusted accordingly.
