Miserable allergy

Can't sleep. My nose is itchy and running. Eyes are watery. The allergy season starts out in earnest for me. Feeling really miserable. I took an anti-histamine pill. I used to cut it in half but now feel that I need the whole pill to stave off the allergy. It should take about half an hour before the pill takes effect. Surely, allergy does not kill but the misery index is quite high.
