KG: I've never tried the spray -- if you do, let us know what you think. I have some Speedo goggles, and so far haven't had trouble with any fogging.

I have a question to you swimmers.
Every time I swim, I get a pounding headache quickly -- my warm up laps aren't even finished and it's throbbing. I notice it the most between laps when I am resting. I have no idea WHY? Anyone else have this trouble?
I figure it could be one of the following things: the chlorine fumes, the pressure of the cap/goggles, the way I hold my head / shoulders... other? maybe the GASPING for air?

Would love to hear if anyone else has / had this problem, and if you figured it out.
