Allergies DO cause fatigue! http://www.healthboards.com/ubb/yawn.gif
I suffer from allergies and yesterday i was so fatigued i almost fell asleep in the bathtub http://www.healthboards.com/ubb/bang.gif
The trick is to try to pull yourself together and DO SOMETHING, whether it be excercise or cleaning, or anything. Sometimes you can cheat and take a nap, but remind yourself that their is life going on all around you and allergies should not ruin your day. I also get achy and suffer from head pressure- which i believe makes me tired because my head feels heavy, thus creating a tired effect. Anyways good luck with you allergy symptoms and don't forget who's boss!
