I do two earlies,two lates, two nights, four rests days. Then repeat.
Earlies: 0700 til 01600 (or until 1700 on fri/sat/sun)
Lates: 1500 til 0000 (or 1700 til 0300 on fri/sat)
Nights: 2200 til 0700
I commute every day - I have no car anymore so have no choice. To be honest though, I love it. The ONLY time I occassionally think ’This is going to be hard' is after the first night shift, when all you want to do is get home and sleep. Even though I think that though, I find once I'm on the bike its easy... well, at least no harder than normal!
I also have noticed massive differences in my sleep patterns being a lot better. I used to struggle to get off nights back onto normal ours during rest days, since cycling I manage this much, much more easily.
