Hot shower saves me - I turn it up as hot as I can stand it - the last 2 minutes of my shower. This heat desensitizes the mast cells - a Yahoo AP group told me about this back in 2006. It's been my saving grace ever since. Sometimes though, something else will trigger it - like water retention or humidity outside and getting into a shower is not an option. 3-4 times a year, during the fall or winter, my AP can get the best of me and I need more than a hot scalding shower.
