There are 2 possibilities.
1. You experiencing bad side effects of your medication(s)
2. You are actually having , some form of a seizure.

I too have blackouts. They are a type of seizure . I also have blur and double visions. Those are side effects from my meds.

That’s why I never do anything that can harm me. I only have 1 or 2 seizures per a month but they can come at the wrong time. I had a seizure in shop class while I was cutting a board and I cut my arm and finger on a saw. I never felt any pain. I woke back up on the way to the hospital and was just like where are we going. So I never use power tools anymore. I’ve taken pills for 31 years and had a few surgeries but I continue to have seizures.

I could be doing anything that's the scary part and I take my medication every day and still I blacked out twice on Christmas

That’s what my seizures are like. However, I won’t even remember being on the floor. I can be busy doing something and at the end of the day I’ll feel like everything went smooth then somebody else will tell me that I had a seizure earlier in the day. I wouldn’t have known that had hey not told me.

You’re having seizures. Something is triggering them. Is there anything you’re doing or feeling when it happens?
