I've never fainted before, just felt lightheaded but last night my OH and I DTD and I didn't feel 'right' then.
After I sat on the edge of the bed, stood up and (according to OH) said "I don't" then went rigid and fell back hitting the floor with some force.
Apparently I had my eyes open but wasn't responding. This lasted about 20 seconds when I became aware and slowly sat up.
All ok except for painful back and teeth (force of the fall I think). I'm currently on citalopram and have been since December and missed that days tablet, totally slipped my mind. Not sure if that's related or if I should see doctor as I'm absolutely fine today?
