I sometimes have allergies, but it's rare these days. Usually only a few days a year that are really bad. Sadly though, no medicine I've found does anything for 'em on those days. Only way I can get rid of them is to practically freeze myself. If I'm lucky enough to have access to a powerful A/C then I get myself down to nearly shivering cold, and they tend to go away. Afterwards I can usually hang on in a cool-ish room without problems. They come back as soon as I do something to exert myself too much, or go someplace too warm. I've learned to somewhat control my stress/metabolism, so if I can stay relaxed, I can tolerate slightly higher temperatures without the allergies returning.
