Brain dead or just lazy?

I read the pregnancy book that pregnant women are forgetful and that's because of the hormone. I don't know if it's true but I've been experiencing being forgetful or just lazy to compose something to post which I think the reason why I sort of have a brain dead lately. Besides, I spend more time watching TV than doing something on the computer (now that I'm pregnant) coz I feel more relaxed sitting on the couch than sitting on a chair. Oh well, I think this too will pass as what pregnant women always say. We'll see. :)
