I don't think I had a problem with this at all before taking my current medication. The medication helps me a lot, but since taking it I experience so much of what people are describing here. I hate it when I'm driving and I've been somewhere far away. I suddenly realise that I have no idea if I've been stopping at red lights, but I suppose I must have been. Once I was driving somewhere in a real hurry, I was running late. I suddenly woke up a few streets beyond where I was aiming for. I have no idea where I was actually driving to, if I hadn't woken up. It was almost too late to turn off before the motorway. Ugh. I feel like my memory is really bad, but I think it's actually these weird dissociative states rather than my actual memory that's affected. sometimes I just cannot remember if I've taken my medication. I'll remember that I walked to the kitchen to get a drink and nothing beyond that. It's not very pleasant!

Although I also relate to watching the TV without actually watching and think that's something I did before taking the medication. Sometimes I do it with books too. I'll realise that I've just been staring at the same spot for ages.
