Today, after a long weekend of sun and drinking - but after a good nights rest and a lot of water - my boyfriend had a short episode of blackout this morning - when he sat forever at a green light when I told him it was green and to go, then just randomly parked the car and got out for no reason in the parking lot we pulled into. I didn’t realize why he did that, thought he was grabbing something out of the back... But then he got back in the car like it was all good. Then about and hour later he blacked out while driving, with his eyes open and seemingly coherent, but obviously not realizing what was going on because he has no memory of us almost crashing head on into traffic (going 60mph), or of me making him pull over and pulling him out of the car so I could drive. Even when I was grabbing and shaking him he was still out of it and almost rear-ender the car in front of us before he pulled over!! He's had a few other times today when he seemed 'out of it' when we were talking and asking me questions to stuff he knew the answer to – with no recollection of these incidents. He had a bad head injury about 6+ years ago, would this have anything to do with it? He is going to the doctor first thing tomorrow, but any insight will be much appreciated.
