Sure, no problem! That's a good idea, I'm assuming because your water bottles are frozen you water stays nice and cold for a long period of time. Strawberries and mint leaves together are excellent. Also, if you don't mind ginger ginger, orange and lemon is a very nice infusion, too. You could also add essential oils to your water if that interests you? Though I've yet to try this so I don't know how good (or bad) it tastes. I believe people use essential oil as a substitute sweetener rather than adding honey. I don't like sweetened water which is why I haven't experimented with it.
