Liquid Benadryl and other anti-histimines help a lot. I have to carry an epi-pin with me now, because my throat swells up, and that is also life threatening. Epinephrin helps the most- too bad there are no epi pills, but if you take liquid benadryl every 4-6 hours and and a 24hr antihistimine every 12 hours, you should notice a difference - I hope. Good luck.
