Usually, I always fall back to sleeping at around 5am and waking up around 2. It feels most natural to me and I've always been super nocturnal. I hate that it makes me feel lazy though.
Occasionally, I lock in this routine of waking up at 7am and going to bed around 10-11. But since I started camming full time, I found I really prefer the evening late night crowd, so I doubt I'll be putting much effort into doing that again anytime soon.
