25 years of the first drop! And unless I am getting ready to sit down and eat, I am not in a place to wash my hands (the car, my classroom, etc.). And like someone else mentioned below, I've been told alcohol can throw off the results, so I don't use hand sanitizer before checking, as it has alcohol in it.
If I'm being real, there are several things I learned in "diabetes school" after first being diagnosed with T1 that I don't do. Along with washing my hands every time I test, I don't change my lancet every time I test. Who can afford to do that?!
