Screwed up while traveling

Recently I went to Europe for a month. I screwed up and eyeballed my pills when packing. I ended up running out of Metformin while I was in Europe.

When I realized I had screwed up, the first thing I did was switch over to daily pills rather than twice a day I still ended up taking no pills for about a week before I got home. I was in Moldova when the pills ran out.

(I also ran out of Vitamin D, but I doubt that'll cause any issues.) I did not run out of insulin or Ozempic.

In the future, I'm going to count the damn pills and make sure I've got a cushion, just in case.

Was what I did the best approach to take given the situation, or should I have done something different?
