Sucks man... How would you rate your overall health?

Not a mini seizure haha it's your muscles relaxing and your brain thinks you're falling and sends that impulse/jolt

See a doctor immediately

A guy in my gym also has these short moments of total black out when lifting weight.

He did a lot of drugs back in the day, but cleaned up pretty well.

If I were you I would see a doctor and explain the situation.

I'm active, I don't do a lot of cardio but I lift 5 days a week extremely hard. I was awake for 30+ hours and didn't eat/drink a lot the day before. I read it could be sleep related.

I used to take prescription painkillers but it has been a long time.

Like most people I get light headed when pulling or dead lifting if I don't breathe lol.. this was completely random though. Kind of felt like I was getting electrocuted, I just had no control over my body besides trying to sit down because I knew I was going to fall!

Seeing my doctor on Thursday, soonest I could get in

i believe increased test levels, ya know from what
can cause cholesterol issues and such.

get bloodwork done. its easy. go to see doctor anyway and let them decide what to do

I had a comprehensive less than 6 months ago and all my values were within normal range, sans the test. I've been off test for 4 months. I will be checking all of this out on Thursday, though.

my dad has epilepsy and never remembered a seizure, also they are a lot more violent than what you are describing

Ya turns out it was low insulin and combination of low blood pressure/not sleeping and how I sat down. Ended up seeing a doc yesterday apparently not dying

Stay safe op!!
