I'm not that allergic to bees, but once I was riding and got stung in the mouth. Didn't hurt much, but my tongue felt like it had a golf ball in it. However, I did get to spit a bee out of my mouth, which was a bit weird. Anyway, back to topic, if you're allergic enough that you need to carry an epipen, you NEED to carry an epipen. Benedryl orally, and alone, probably wont cut it if you're that allergic.
