I've been suffering from sleep paralysis for years. The thing is, I only ever have episodes when I take a nap on the afternoon. I'm not sure if it can be related to digestion, in some way. All I know is that it's terrifying the first times it happens, and even now that I've gotten used to it, it's still pretty bad, and waking up is a nightmare. Sometimes I get caught in a loop where I try to get back asleep and then I go through the whole thing again. Napping is supposed to help finding some lucidity and yet, it ruins my day most of the times.

Anyway, there's a lot of good advice in the post. Nothing that has definitely solved it for me, but a lot of solutions that can make it better, if anything.
