Do not operate heavy machinery... or deliver sermons

My allergies have been acting up lately, and the standard over-the-counter medicines haven't been working, so I got a prescription for a stronger drug. It came with the common warning about causing drowsiness, etc. Usually, those side effects don't apply to me, but this drug knocked me out. Unfortunately, I found out the hard way when I took my first dose in the morning before today's sermon. I don't know how I made it through, but several people asked me afterwards if I was all right. We all had a little chuckle when I told them about my allergy medication. Now I know when I should and shouldn't take it!
