Im in a fix right now. I usually during the day drink HEAPS (several litres sometimes more) of soda water. Soda water contains potassium and I find I can drink it in large quantities without it making me sick. Today .. my support hours ran out by the time I got blood test done and got a vaccum I needed in the other town where my blood tests had to be done (no shops for vaccums in my area so hence why I did that today when out in other town). So now I have no shopping and no milk or soda water to drink (as I just finished off the last 3 bottles I had today) and its sooo hot so Im thirsty as anything (sweating a lot today... thou usually I often dont sweat well).. i need to make up something I can drink and drink a lot of which wont make me sick in the quantities I drink.. Help please. (im about to start sculling plain water as I dont know how to make up what one should do in this situation). Im going to start going downhill fast in this heat if I dont find out what I should be drinking as I cant drink water to the amount I need to do easy (without making myself start to get sick).
