A Camelback may solve the drinking problem, but there are other reasons you might want/need to remove a hand from the handlebars for- so it's probably better to work on your balance so you can ride comfortably with one hand for short periods. You might want to one day be able to unfasten your Camelback and sling it around the front of you to dig around in it for something, without stopping! :-)
