Yes. I am hydrated. I'd die if I wasn't drinking water at work. Seriously.

I used to get them while laying in bed. If you can stand up immediately and put pressure on the heel of that leg, it'll subside quickly. I've always attributed it to dehydration. 🤷♂️
I'm very rarely dehydrated. And yes, standing can help, but... Getting out of bed at the time would have been... Difficult.
lack of salt and dehydration are definitely factors. i am pretty sure there is some form of chronic nerve damage caused by seed oils and other things like artificial sweeteners that contribute. i don't get them very often since having like 2-3tsp of sea salt with 3L of yoghurt/milk per day (in 3 meals of course) but even then, after a few beers/wines the next day i sometimes get one. so that points at the dehydration route, and also to some extent the salts, but also nerve damage because alcohol depletes B1 and this causes signalling problems with other muscle systems. once it starts to affect your eyes you know it. i get double vision fairly often and it also seems to be affected by dehydration, salts and poor nutrition.
