Hi Kevin. Thanks for doing this twice. Sorry about the confusion. Medication adherence, as you know, involves many factors. You listed some of them. With hypertension, people don't feel sick, so don't necessarily notice the difference when they are on the medications. Also, some of the medications have unpleasant side effects. People with less insurance coverage have to get whichever pills are covered by the plan. The pills might change over time and the appearance can change, which is confusing.
