Tab was my first diet beverage. I was 13 or 14 and going to an orthodontist in a building that had a coffee shop on the ground floor. At that time saccharin was the only artificial sweetener around and Tab of course contained saccharin. Tab tasted good going down the gullet, but for hours afterwards it kept coming back and it didn't taste so good the second or third time around.
Anyway, no more Tab for me. Of course, later other sweeteners came along that were more digestible. But eventually, I got away from diet soda and later soda in general. I'd rather have water or tea.
