I wear a Camelback also. In the desert heat of So AZ, I start out with plenty of ice in it. I drink at least every 15 minutes while riding. Actually I drink something every so often even when I am not riding if I can.

When riding on the road, I will add ice whenever I stop, at gas stations, convenience stores, etc.

I know it's hard to believe, but summer seems to have arrived here in the UK - sweat was pouring off me on the hills this morning.
