Did someone drug my lemonade?

I got home from work at around 3.30, got myself a drink of lemonade and promptly fell asleep.

I woke up long enough to take a bath and answer a couple of emails, but I still feel like I should just crash. I just watched two hours of television and I can't even remember what show.

It's quarterly results week at work - which does explain why I'm a tad stressed but I've never reacted like this. I'm not headachey, I don't have a temperature or anything like that. I'm just...65% asleep.

Someone must have dropped valium in my lemonade. I swear.

I'm off to bed.
