Daughter and I made pill lists with dosages so that we don't forget things (easy to do with cognitive dysfunction). We fill our big pill cases once a week so that we don't depend on feeling well enough to do it right every day.
We keep one bin with our current medications and supplements and the pill lists. We have another for extra bottles and things we are not currently taking so we don't get confused. We have a whole routine set up to make sure we get the right meds in, don't duplicate, and get more ordered when we're running low.
The current meds bin is on the left. Take out one bottle, check the list, fill the pill case, and place the bottle to the right... unless it's running low in which case it gets put in the middle of the table. When everything is checked off the list and in the pill cases, we put all the bottles on the right back in the bin. Then we immediately go and order the meds/supps we were running out of. If we don't do that immediately, we forget and run out.
Once those things are ordered, the bottles go back in the current meds bin.
On weeks when cognitive dysfunction is not a big issue, we do this in front of a favorite TV show to reduce the boredom. On bad cognitive weeks the distraction results in screw-ups so we leave the TV off.
It's relatively painless and efficient and reduces stressful screw-ups.
