Maintaining Medication/Vitamins

This is one of the toughest "health" behaviors to maintain on vacation for me. Because my schedule is completely different and I am living out of a tent I have a hard time remembering to take vitamins/medications. In the mornings, I am busy prepping the van for departure or planning the activities for the day and completely forget my medication. At night, I am focused on getting to bed after a long day of driving or hiking and can't seem to remember my vitamins. I have started to pair my medications/vitamins with brushing my teeth because I always remember this - I have started to put them in the same bag. Such a simple thing--why didn't I think of it before?
