I had to get my drops after the Japanese nuclear accidents caused by the earthquakes and tsunami, so my fellow Americans were buying up the drops to supposedly protect themselves from the released energy.
I was worried I wasn’t going to be able to buy them. I got lucky. My pharmacy had a part-time pharmacist who also worked about 75 minutes away and happened to see one, so she hooked me up. I guess these things work out one way or the other.
