My stomach hurts sometimes before sz’s start!

I get nauseous!

I don't have that feeling. But I know that is an aura that you may feel seconds to a couple minutes before seizure. I guess for some it may form during the seizure and feel after. You may be able to get the answer for that question in the search box of computer. I know I type in "what do right temporal lobe complex partial, epileptic seizures auras feel like" it tells me 1st actions during seizures. As I stroll down it tells me more, such as auras. Which are odd taste or smell, hearing something not there, DeJa'Vu, feeling as if on roller coaster, or falling down. Hope that may help! wish you best of luck on your quest!🍀

No, I can't say that I have.
However, I do take medication because of having issues with my swallowing.

No problems with eating once I am aware of what has happened.
