I've taken the wrong pills before. Part of what helps me is I get out my morning pills when I get out my nighttime ones (since I'm always running late in the morning). I also know (silly as it may seem) how many pills of each color and shape I'm supposed to take when. For some reason that's easier to remember. I also always keep them in the same order (this is very easy because they're laying in a small safe on the counter - kept them safe from me when necessary and now keeps my brother from stealing them).

Don't feel too bad...it's certainly not the end of the world... a month is just a month and everyone messes up every once in a while. I took my nighttime meds one morning...morning became night very quickly lol.
