Daily Night Soda

So i have managed to quell my soda consumption down from 64 oz to just 12 oz...20 if i'm gaming a day.  This is an accomplishment.  I have replaced my soda with copious amounts of doctored water and green tea.  However, nothing is as soothing and relaxing as having that nightly soda either with dinner or right before bed to put me to sleep.  Caffeine has never treated me like it treats some people like a cruel mistress that keeps them awake at night.  However,  it just seems nothing chills me out like a soda.  So i drink one at night and that's it.  Its almost like a treat for a long day.  I won't ever give up soda... i like it too much but cutting down from my usual two liter a day to a 12 oz can is a big deal.
