I use a 7 day organizer that has 4 times per day, and I set it up as two weeks of meds, am and pm. This doesn't actually mean I remember to take my meds always, but it does mean I only need to set it up once every two weeks. Also, sometimes I cannot remember if I took my meds, so it is good to check. I carry my case in a ziplock bag when I travel. TSA has never questioned it. They question the Coffee Mate - powdered milk - every time though!!
