I used to drink the normal citrus rockstars as I have a like for sour tangy tastes. Then I noticed these in the store and decided to give them a try. Oh wow they're so good. The tangy taste still there. It still tastes really good. For some reason I feel an extra kick (more so than other rockstars) and I'm awake longer than I usually am with normal rockstars. Could be just me though :)
