I have been body building for the last 4+ years and have learned that vodka sodas are my best friend. I like the taste (or lack of) of soda water so it doesn't bother me but at home, I use La Croix's (YAY for the millennial drink). I have friends that mix crystal light packets or Mijo to theirs for flavor. Another good choice is coke zero, sprite zero, fresca or diet tonic.
