I've never had a TC to my knowledge, but do have tonics and complex motor seizures. I have had the odd one where I am almost euphoric after. My seizures are nocturnal and to have that feeling in the night can be compared to having woken after an absolutely amazing dream, and then fall back asleep fairly quickly. But then when I'd wake up the next morning I'd feel typically post-seizure and lousy: weak, out of it, unmotivated, ticked off (lol).
