I made a post a while back about the pressure change affecting my head. I know exactly what you are saying about being worse in the winter. I was born and grew up in WI, and stayed there for 5 years after my accident. When I realized that it was the weather, I moved to central WA. It was much better there, but I still only did really well in the summers, with winters being unbearable.

Now I am in AZ, and just completed my best month in 7 years! On my head chart, I can see a dramatic decrease in symptoms in each of the past 3 winters that I have been in AZ. I notice an immediate relief, but it seems to take a good month for all of the symptoms to resolve and level out. San Diego should be even better, as it is even more stable. We were in San Diego this past weekend, and I was able to enjoy life with my family, instead of just trying to survive. Needless to say we are house shopping again...
