der Heuschnupfen

The problem with a sudden burst of hot weather after a long period of cold is that it feels as though all the flowers are in bloom at the same time. Hayfever (Heuschnupfen) is killing me. Also, I swear over-the-counter antihistamines are like...A BILLION TIMES stronger than German ones. I had to take 3 in a 24 hour period yesterday :(
