yep, im the same.

I was very tired and exhausted for the first 3 months or so...then i had 2 months of being fine, and lasting the whole day through...and now...i hit 22 weeks and im feling the tiredness again....

I can sleep in til 9.30 in the morning, get up, start housework, and be yawning by lunchtime. I try not to nap, as it usually makes me more tired.

By dinner im getting tired and sore eyes, and by 8.30-9...im in bed...

I thought it may be over sleeping, but if i get up at 7am...im even worse off...so im making the most of my 9.30 sleepins...
