I adapted to it by shifting my IT work to remote + after hours.
Sleeping is one of the most important things I can do for myself.
Thoroughly exhausting exercise in the afternoon is key for me. 12 or 1pm until 5pm
I prefer to work until about noon. When inspiration or necessity strikes I will code day and night.
Weekends it can very but any typically around 4-6am to 9am-4pm.
Wake up: 70% at 0630, 20% at 0530, 10% at 0400.
