I don't drink any coke/pepsi, but I do make and drink Kola and/or ginger soda almost daily. I typically use Liber brand Kola (and ginger) syrup (but sometimes mix it up) mixed w/ club soda or san pelligrino. Way less sugar (and it's real sugar/not HFCS), and it works wonders for my migraine and stomach issues (my dad's a pharmacist, so I grew up being given coke syrup for my stomach and head aches).
