did you try benadryl?

or if you have a prescription for clarinex you can take 2 of them and see if it helps-- i'd only try this once, i'm afraid that taking more than recommended for long periods of tiem might do harm, but i've been told every once and a while it is ok. i have also been told by a D.A. that taking 2 can help if someone is having an allergic reaction.
