Both my long and short term memory are ruined. I don't remember things which I would have done 5-10 years ago.

I struggle to find words sometimes. I can be talking about a subject which I'm knowledgable on, but my mind will just go numb mid sentence. I have to struggle to think of what I've said, and what to say next. This is obviously pretty embarrassing if I'm talking with customers and trying to sell my product.

And time. I don't have any real concept of it anymore. I see time as just a big lump. I don't really see days as days or weeks as weeks, months as months etc. it's all just one big lump of time. I guess sleep deprivation doesn't help this.

Can anyone else relate to these things?
