Apixaban can cause tiredness.

If snoring is interrupting your sleep, you can wear an inexpensive mouth guard on your upper jaw and sleep in an inclined position. This makes it much harder to snore.

Well I don't snore to speak of but I've been on Apixaban a couple of years it would be odd for it to start giving me issues well other than I have to be damned careful working at my forge

Edit.. I just had an idea, about seven weeks ago I got new jets for the forge and also started doing experimental work with copper Damascus and some other alloys. Maybe I'm getting exposed to something new there?
I'll have to have a think about this.
