rost, my friend, you may not be ten years old - but your taste buds are. I shudder at the thought of drinking anything as cloyingly sweet as Dr Pepper even once. Several a day? Accept the idea that you'll be diabetic.
It requires a different thread, but a discussion of what we drink and how much might be worthwhile.
I drink two to three cups of coffee in the morning. I drink unsweetened iced tea or Arnold Palmers when I want something besides cold water the rest of the day. I'll drink maybe one can of ginger ale and one can of beer a week - usually less. I have four alcoholic drinks a week (weekends and Wednesday). And I have a quart of 2% milk, mostly on cereal, each week. That's it.
