I took tons of these tablets a few years ago when I go the stomach flu, but they are needed when you get any stomach upset involving diarrhoea, heavy colds and the flu. I tend to take a tube of these, or just a few, when I go on holidays and I know for sure that I will be doing lots of walking, trekking or strong physical exercise, as I can dissolve a tablet in a bottle of water and carry it with me ready to drink. Besides this sort of tube, when empty is most handy and you can reuse it to carry small things inside (small coins, small tools, other pills, rolled banknotes, whatever small) and rake them with you safely.
My only complaint is that the product is expensive, about 10 bucks the tube. That is not much if you are buying just a tube for a trip. However, if you are sick, especially with gastroenteritis, you will be taking lots of these. I wonder why the manufacturer hasn't thought of providing customers with bulk packages to save money and visits to the pharmacy in those cases.
They come in at least two flavours and are quite pleasant to drink.
