I have two piles of meds I take 12 hours apart: the Big Pile and the Little Pile. Since my sleep schedule is completely chaotic, however, it's sometimes hard to remember whether I'm taking the "morning" or "evening" dose. I think right now the nighttime dose is the Big Pile. Unless that was 12 hours ago, and I've just accidentally OD'ed. I used to keep all my pills in neat little AM and PM boxes, but I gave up on the extra hassle ages ago. Here's hoping I don't start feeling bizarre.
