Dr. Pepper is for the real mad scientists.
I have started to drink Dr. Pepper more often lately, probably because of S;G... Too bad they dont sell them in bigger bottles in Finland than 0,5l...

Basically i dont taste ANY difference between Pepsi-Coca-Freeway cola, but I only know that that freeway is cheapest (2,0l ~1,80€) and coca-cola is the most expensive (1,5l ~2,60€), Pepsi is somewhere in the middle (1,5l ~2,40€).. So I usually go with the cheapest because I get more with less money..
