Even cheaper if you make your own using LoSalt.
I was going to link to this, but easier to copy...
Dioralyte contains glucose, sodium chloride, potassium chloride, and disodium hydrogen citrate. I think the latter is just an antioxidant. LoSalt is sodium and potassium chlorides, but isn't quite the right proportion, so I add normal salt to boost the sodium content. If you look at a sachet, it tells you the proportions of each, as does the LoSalt pack. Having said that, the original formula for rehydration fluid was "a handful of sugar and a pinch of salt", so I don't think it is critical.
[Later]
Dioralyte per sachet: Sodium Chloride (NaCl) 0.47 g; Dextrose Anhydrous 3.56 g; Potassium Chloride (KCl) 0.3 g; Disodium Hydrogen Citrate 0.53 g
LoSalt is a blend of at least 66.6% potassium chloride and up to 33.3% sodium chloride.
So Dioralyte has 1½ times as much NaCl as KCl, and LoSalt has 2 times KCl as NaCl. To get the proportions right you need to add more NaCl. Too early in the morning for sums.
[Later still]
Ignoring molecular weights...
3g LoSalt is 2g KCl and 1g NaCl
add 2g NaCl (normal salt)
Total 2g KCl and 3g NaCl, which is correct ratio for Dioralyte, and enough for half a dozen sachets with the addition of about 20g of glucose. I think the disodium hydrogen citrate is optional, but perhaps someone knows better.
The problem is that it doesn't mix evenly, so I just mix a tiny quantity with a mustard spoon when I need it, in ratio 3:2:20
Just about one of the best rehydraters around is ordinary full fat Coke, and it includes most of the necessary salts etc. as well.
Much more pleasant to drink than some other salty solutions and you can add stuff to enhance the taste/effects too.
