What do you guys and gals do about water bottles and the gym? Do you take the same bottle and just top it up, or do you take a fresh one for each trip? If you use the same bottle and top it up, do you have to clean it at all? and if so, with what? The reason I'm asking is that I normally take a 500ml bottle and top it up from the water fountain in the gym, but this morning I caught a whiff of the empty bottle and it stank!
