I am embarrassed to say I am a bit addicted to the carbonated soft drink Mountain Dew.
It's the BEST!  I love it, too!  I drink Diet Mountain Dew for breakfast!  
Really? Me too! I drink as many as 4 per day. There are other citrus soft drinks, like Mello Yello and Sun Drop, but I like Mountain Dew the best!
Does Mountain Dew have the most caffeine?
Good question -- I think it does. I'm sure more caffeine has been added over the years since it was first invented in 1940! 
Wow - I had no idea it's been around that long! I'm glad our modern FDA hasn't banned it for the artificial food colors and extra caffeine!
Ha, I know. Probably pretty toxic by many people's standards. Did you ever try the cherry flavor called Code Red?
I've never heard of Code Red? Is it by the same makers as Mountain Dew?
Yes, Code Red came out in 2001. You don't see it often. I wonder if it has been discontinued. 
Does it have a lot of caffeine?  I need to go look for it because now I'm curious.  Guessing it's cherry flavor.
