Just reading this, the right side of my head is twitching in sympathy pain..

I'm another memeber of the migrainer club. The only trigger I've found is dehydration. So I try to drink lots of water. Unfortunately, another trigger I can't control is smells. I think I'd take the visual premigraine than a hyperactive sense of smell. You notice thing's that normally wouldn't bother you, which becomes a downward spiral. Last week I had a H.A. started by someone's cologne, also triggered an asthma attack. Had to walk out of the meeting. "Excuse me sir, but you put on WAY too much aftershave, I need to move, you stink." (OK, I only thought it)

So I guess I'm saying, drink plenty of water and get some fresh air.
