I have had so many times this year when I screwed up my meds (filling the pill box). I've been seriously frustrated with myself over it. What I've been doing is what Christina suggested...1 bottle on the table, pills in box...Next bottle on the table, pills in box.
Slow way, but at least it keeps me from getting everything mixed up. And yeah - for me, it's that cognitive thing, too. I can't connect the dots.
