6 weeks and feeling less tired

I have a new theory since coming back from the residential - I need to eat more... still trying to do Weight Watchers has been sapping my energy I think - although I was surviving on a daily basis it wasn't much fun.
I ate well on the school trip, and feel less tired now. Also having eaten a decent lunch at school for the last two days, I'm not having to nap in the evening. Saying that, maybe it's just a coincidence and I'm just naturally less tired at this stage of the game.
I really hope that this morning sickness lark is genetic, as mum said she had none with my brother or I!
Busy weekend - rugby all the way (not playing obviously) but coaching for school, then on a coaching course too!
