I've had sleep paralysis since I was a very young child. It has an irregular pattern with me. Sometimes I get it 4 times a week but sometimes only a a few times a month. I don't know if you can ever get rid of it for good. I actually have a sleep study booked at the hospital. They monitor your sleep and try to get a better idea of what causes your problems.
Keep track of when you have it. A lot of the time people find that you experience it more when you're not getting enough sleep or aren't on a regular sleep pattern. It is always good to look to see if there's any patterns. I've personally just started keeping track of them.
I also read somewhere that some people are treated with antidepressants because for some reason it can prevent it from happening.
I'm not all knowing about SP though, even though I've had it since I can remember. I haven't really looked into it until recently.
I also wanted share my thoughs on another sleep paralysis issue. Some people think that they're having an out of body experience or are being abducted by aliens. I just want to remind you that you can hallucinate during sleep paralysis. You can feel things, hear things, see things, etc. that aren't there. I personally believe that there is a logical explanation to this all.
Hopefully we'll all be successful in gaining more knowledge about this annoying condition that we experience, and are able to find solutions that we're seeking
