I wonder. The 2 tablespoons of sugar should give a certain amount of energy. A squirt of lemon or lime juice doesn’t have nearly the amount of sugar, so it may taste ok but does it really give the surge of energy that you get with sugar?.

I go out running at 11 AM and 2 PM. I drink that electrolyte solution about 10:30 in the morning and at 2 PM. I can still jog all the way around the track without stopping.. Even at 3 PM after going to the gym, I can do it. If I don’t drink that liter of electrolytes, there’s no way I can Jog more than halfway around the track at any time without having to slow down and walk half the distance.

Where we live we don’t get heat waves, I’m lucky if it’s 70° here which it seldom is. Maybe that lemon/lime juice can quench your thirst a little bit because of the heat, Does it really give you much energy if you don’t put a significant amount of juice in?
