@GracieJ Really interesting stuff about Apollo and the time a blue light is effective for you. This may correlate with info in an article I just read. Note, the article's tone isn't the best, but there's some useful info in it. The advice is for delayed sleep onset (probably the opposite of your sleep problem, but the advice may reinforce the notion that different people need melatonin at different times):
Your sleep schedule does sound very complicated. I wonder if you may be dealing with two different sleep disorders? One would be your short 18 hr cycle, maybe Advanced Sleep Phase Syndrome? Second would be either the early-waking (more info) or the maintenance type of insomnia. I know people who have the former.
As for why your sleep schedule boomerangs, maybe when you're trying to stay up, you're being exposed to blue light in the hours before your bedtime? Blue light suppresses melatonin and therefore sleep. I can't tolerate blue light very well, period. Florescents and LEDs are painful. I tried blue light therapy. It gave me severe headaches. But recently found it may be keeping me up. This is why I'm looking for a blue-light-blocking filter for my laptop for use in pre-bedtime hours. Since both of us have counter-intuitive sleep problems, it's great that you think in off the beaten track ways. I hope you transition fully to this dastardly DST.
We also use melatonin, but not as a sleep aid. Instead, we use it to alter people's circadian rhythm, and therefore, we give it 5-7 hours before desired bedtime and we use small doses (0.5-1.0 mg). And I always recommend that they try this at home the first few times in case it makes them sleepy right away.
