Chrissyjo, just to share my experience, I got headaches at first, and awful too, with a lot of sound sensitivity. I cannot tell you to stick at it because we are all different and I'm not a medical professional, I do wonder about the processes that cause the headaches as well.
All I can say is I took a break for a week and then braved it again, tried them, got the headache, missed it the next day, etc, and it was a bit of to'ing and fro'ing like that. So I never did 7 straight days, but now I'm good with every other day, everyone is different to what they need, that works for me now, but at the beginning I honestly thought I wasn't going to be able to use vagifem. i'm still a bit sound sensitive, but not the same extent. Also I had hair loss to start with, that's also stopped, I was surprised it stopped.
Hope things work out for you whichever path you decide to take.
