Excessive Sleep in Winter (aka "I'm pretty sure I have you all beat here")
(cross-post from ST)
Does anyone have experience or knowledge about excessive weekend sleep during winter months? I live in Canada, and for a number of years, I have a winter month pattern where I'm able to function well enough M-F, but come Saturday and Sunday, I sleep. And not just "boy, did I ever sleep in today - three extra hours!" I'm talking occasional numbers between 14-24h on Fri night into Saturday, and 12+ Sat night into Sunday. Solid. If the alarm goes, the battery will run out 'cuz I ain't responding. At worst, let's say 5-10% of this comes from being a lazy bastard, but I now just scratch plans to do anything except sleep and train on weekends, cuz that accounts for the time I have. Come April, I'm good to go and can jump onto a bike at 7am Saturday and Sunday morning and have productive weekend days again.
I've gone for sleep studies, had blood tests, and things come back normal. I've tried to manage SAD through the usual remedies including bright light therapies, to no avail. I've looked into hypersomnia, but this applies more to regualr excessive daytime sleepiness instead of the sleep debt that I live with. I've also experimented with earlier or adjusted midweek sleep to try to get in front of the debt to no avail. Short version: Unless there's a paying job that I have to wake up to go to, I could probably sleep 24-7 until April.
Any insights?

I've always been one that can sleep pretty much anywhere, anytime. I'd imagine that 2/3 of the flights I've ever taken, I don't even remember taking off because I fall asleep so easily.
