I was getting those shocking headaches up until about 20 weeks too. When they got really bad I'd take two Panadol. Like BD I'm finding that my eyesight is worse than normal and I'm having to wear my glasses more. Thought it was just me, but maybe it is pg related????

Fess is safe for use in pg, I used it when I had a cold early on. The pharmacist recommended it to me. My only problem was that it would then run down my throat and make me throw up (my m/s was pretty awful at that time, it didn't take alot to make me chuck!). But it did clear out my sinuses.
