I started by pulling one or two doses out of each prescription as it was refilled until I had the target amount (7 days worth).

The beginning of this year when we filled the first prescription of the year for each med I rotated the old stash out and replaced it with 7 days worth of the new.

It takes some time but once you've got the amount you need rotating it is easy.

Fortunately, we don't have that many prescriptions.... yet.
