Can I go to bed, please?

I am really feeling pregnant. I still can't believe it. Nausea has become part of my life and hopefully won't stay very long. I don't care though. On many pregnancy sites, they say that morning sickness really kicks into high gear in the sixth week. I'm hoping that is not the case. With DS, I had one day of sickness and no more. I am already finding it hard to concentrate at work and for school work. I fell asleep on a teleconference and couldn't do anything to snap myself out of it. I even took a stroll around the floor, came back, sat down, and five minutes later Out! It is so not fair that caffeine is not allowed! Sleepiness is everyday and rest is my friend.
