I have a free running sleep disorder, which means my 'natural' sleep cycle is longer than 24 hours. Basically the wakefulness period my body wants shifts around the clock every day. I force myself into a 24-hour schedule because I don't like to live like in isolation half the time (roughly half the days I want to sleep during the day and stay awake during the night). That usually causes all sorts of trouble at work with me running late, or having to take a nap during the day in order to be able to function properly, but I have a somewhat flexible schedule and that helps me coping. I also often fall asleep on the train and miss my stop, and then I arrive even later to work. While troublesome, I can handle this forced 24-hour schedule and I've sort of learned to live with the consequences.
When something interferes with my forced 24-hour schedule, though, it gets worse. If I go out at night and stay a bit later, if I travel to another timezone, or if I take medication that interferes with sleep, my body wins and I end up sleeping at unconventional times for unconventional durations. With some effort I can return to the usual forced schedule the following day.
In the past week I had a few NMRs. One of those was because I had to go to the hospital due to what turned out to be a gallbladder inflamation, and I it had to be removed. And of course the meds threw off my sleep cycle again. The rest of the NMRs, well, I just slept through the phases ("oh, I still have twelve hours; I'll finish what I am doing and punch in my orders in a couple of hours" followed by falling asleep after an hour and waking up twelve hours later) and for that I want to profusely apologise. Unless something bad happens again and I have to take sedatives, I don't foresee another such episode, but I understand if someone would prefer that I find a replacement for some game I am in. Please PM me if that's the case.
And once I am done with the games I am currently involved in, I will not play in anything with shorter than 48 hour phases as shorter than that clearly won't work for me.
