Flexeril Makes Me Stupid

Tonight, I showed up two days early to take care of a friend's bunnies. I checked my records, seems I copied it down incorrectly from my written event calendar to my computerized one. And had it in my head that way, as well. An unusual mistake for me. Ugh. Poor Tina. Scared the ever living hell out of her. *Sorry!*Sorry!*Sorry!*

Ladies and Laddies who've been on Flexeril, is this the norm? If so, any advice?
