Yep! I do it all the time. I have a pill box too but I have to pay attention. I may pop a pill into my mouth, instead of putting it in my morning slot. I figure might as well take it now.

Then I look in the slot and nothing is there. Did I take it?..or forget to fill it? I could write it down and check it off, but sometimes life is just too busy to do everything correctly.

Like my thyroid pill. I have to take it on an empty stomach, and drink a full glass of water and wait one hour before eating. Now my problem is, what time did I take it? Can I eat yet?
