Lightheaded??

Hey there everyone. So each time I've quit K, I have developed severe lightheadedness within the first few days after I stop. It doesn't happen all the time, just when I have been sitting or laying down for a while and stand up quickly. I know this happens normally to many people but it's extreme for me each time I have quit. Just curious to see if this has happened to anybody else? Maybe has something to do with always having high blood pressure when on k? Then when you get off, your blood pressure is lower? Anyway, just curious. Much love to everyone out there!
