I am also trying to cut on sugar that comes from sports drinks. I recently tried Hammer gel in raspberry flavour and it's good. I mean even compared to GU it's better. It has only 2 g of sugar, now compare it to 25 grams of sugar coming from Gatorade. If you check out Hammer website, they have a recipe that combines their Heed product with water and something else and thats basically to sabstitute for Gatorade. Good luck with root canals!!!
