What happened?

This happened a couple years ago, and may be related to the supplements I was taking.

I was taking these Choline supplements to try and help with memory. A week after I had been taking them, I woke up with my eyes rolling around forcefully and I could not control them. The room was zig zagging. I screamed for my mom and It eventually stopped and I went to the Er and they said my potassium was low ( I’m fairly certain that was due to an eating disorder.) What happened with my eyes though? The doctor never said anything about it. Was that a seizure? Could choline cause that?
