I acquired some Passover 7-Up made with sugar.
Followed the directions and to be honest it's actually quiet tasty and refreshing.
It's just a Lemon-Lime cream soda, that is less creamy versus more sweet milky alka-seltzer like.
I have been recovering from kidney stones for the past 3 weeks, topped off food poisoning. I made one and it was actually amazing to my stomach and general constitution.
I'm a fan, especially as a remedy for an upset bowels coupled with thirst.
