For the most part none.
I never acquired a taste for coffee, but I never really tried. To be honest, I don’t know if I’ve ever even drank a full cup of coffee total, in my life (and I’m not exactly young...).
and the only soda I really drink anymore is Ginger Ale.
I used to drink soda as a kid but I don’t really drink it now. Maybe I’ll have a few sips with dinner if I’m out somewhere and that’s the only choice but that’s about it.
Caffeine tends to make me feel jittery anyway.
