I've tried the diluted OJ with a pinch of salt and it worked fine. I don't drink Lucozade sport any nore because it tates horrible, though I did drink it at FLM - thoughts of what would happen if I didn't, and I didn't want to carry my own drinks.
Lucozade has to be a lot better than that Liquid Power stuff they had in FLM 2001, I thought I would be very very sick if I had to drink any more of that stuff, yuk.
