Don't let yourself down, there are much worse diseases out there... Not to ridicule AS, but one can live with it (most can...)
- Get away from red meat
- Check for Gluten intolerance
- Check for Histamine intolerance
- Check all specialized Practitioners until you've found one that medicates you perfectly
- Get a good physiotherapist and finally
- Train, train, train, train your *blush* off
