@Narusan Thanks! Still my main question was: Would this question be on-topic on health.SE? Or is lifehacks.SE more suitable? (I'd guess that latter is probably a better choice.)
And maybe the question has already been asked on some site - just my Google-Fu was not good enough to find it.
But if there is no such question, I suppose suggestions what to do in such cases might be useful for others, too.
Thanks. When I have a bit of time, I'll try to post it as the question. (That is, unless somebody does so before me. And I will try to search once more before doing that.)
