I have them lined up in a certain order in their bottles on a shelf in the kitchen, and I keep track of AM, Noon, AM/PM and PM dosages by turning bottles on their sides or upside-down to keep track of which ones I have taken or are next (such as at Noon) or still later (PM). For a certain med I used to take every four hours throughout the day, I used the hands of a non-working clock to keep track of dosages. For my OTC supplements, I use old prescription bottles I fill with dailies every couple of weeks and then take one of those bottles along with my one Noon med each day.
