I too had awful headaches for 4 weeks straight - i'd literally wake up with one, and although I don't like taking panadol at the drop of a hat (even when not pregnant) i was seriously going through a pack every few days just to survive.

Thankfully they've gone now, as has most of ms as i'm taking ginger tables (OMG SAVIOUR).

I hope they go away soon hun! as per everyone else: water, try not to stress and get lots of rest.
