Anti-histamine knocks me out, so lately I've been using Azep Nasal Spray. It can make you feel a little bit light-headed and vaguely stoned - which can be either good or bad - but not so much drowsy. And it works friggen quickly. You can feel your nose cooling and the swelling going down within seconds.

Like all these medications, you're better off using it before you leave home, before the symptoms set in.
