There's more than one form of periodic paralysis linked to potassium and each responds to different triggers and has different symptoms.

I do not always have an attack from eating carbs. One of my biggest trigger is rest after exercise. But I find that I react a lot stronger to a combination of triggers. If I combine a few of my triggers, I will definitely have an attack. Of course there are a lot of medicines that trigger attacks, those attacks are the scariest.

Try keeping a diary without changing your normal routine. It might be helpful. Then change your diet or routine one thing at a time, that will make it possible for you to find your triggers.

If you bring that without bringing in any information about a certain disease to your doctor, you're more likely for them to listen. They tend to hate when their patients come up with the answers before they do. Do you have a good doctor you're working with?

I hope you find your answers soon! I'm always here if you need someone to talk to.
