I see the doctor every 3 months. He gives me a RX that last that amount of time and then some. Some overlap there. I get a month of meds by prescription that I can stock up save for future supply. That is how you add up your medication stock.
Another way is just get prescribed the max dosage and take the lesser dose required. That will extend the time your medication will last.
Cutting costs is being prudent. Like knowing cost per pill, the weight, many factors to consider. We want to save and stop foolish spending, keep an eye on cost. Know the math can’t nothing block your path. This goes for earning money in general, same economic model applies. One lacking needs to be more astute when it comes to finances. Because being financially wealthy is a road to good mental health.
