This is how it works for me with any other video games that I have to play. I get thirsty very quickly which is why I had all sorts of fluids at home all the time. But I usually drink water when playing games.It's not just only Halo games that I have to drink when I'm playing. It's something that I do with with all the video games I play. I always feel thirsty all the time.
My favourite drinks whenever I am playing Halo games or other games are water and soda drinks. It keeps me hydrated and active though I prefer more water to soda drinks.
I am good with water though than soda. Soda will make me to have urge to be having sweet mouth so I take little soda and much water.That is the highest that I can drink when I am playing games as well. I just don't enjoy taking alcoholic drinks when I play games.
