So last night I wanted something to drink other than water but wanted to avoid caffeine so FI got me a Diet Sunkist Orange soda. Newsflash to me! Orange soda has caffeine in it!! This just seemed so odd to me. I thought that soda that has caffeine is either dark or yellow (mt dew) or obviously caffeinated. Anyway, I drank this 20 oz. soda at 8:30pm (don't normally drink more than a 12 oz. can in the beginning of the day if it has caffeine) and was up until 3am! I couldn't figure out why until FI called me at work today and said "hey so I know why you were up all night..."So if you didn't already know... it's got caffeine and lots of it.
