I've decided to have a coke for dinner. Caffeine - powerful stuff!!
Good luck breaking the habit, man! I remember getting the headaches when I quit coffee for a while.
You mention Coke - for me that's the single toughest habit to break. I've quit smoking, drinking alcohol, and even managed to drop coffee for a while. But the Cola habit is the only one I couldn't get rid of. I did manage to reduce the quantities that I drink, but I still have at least one every day.
OTOH, I drink phenomenal quantities of liquid every day - water, milk, orange juice, vegetable juice, gatorade, sparkling water, coffee (usually 6 of them or more), cola - I basically always have something to drink at hand. So I guess cola accounts for a negligible portion of that.
