I quit drinking all soda (down from ~5-8 12oz cans per week; which I thought was low) a few years back, added more water and vegetables to my diet and now I rarely have AR. The only times it flares up comes from when I travel for work and don't have access to the best food selection.
Also, most AR comes from an imbalance in your stomach pH so you might look into the foods you are eating. It's the sodium in sugar drinks (Juice, OJ, Gatorade, etc.) not the sugar that turns up AR.
