Generally I drink lots of water but in the summertime, diet soda seems to be the thing to quench the thirst. I also love club soda am kinda starting to prefer that for the different taste. My fav is citron vodka, cranberry juice and a splash of club soda.
I have even been thinking about getting one of those carbonators as I most of time just want the carbonation and not necessarily the cola. Having been a bartendar, I learned about the secret cure for sout stomach, bitters and club soda...I drank/drink so much of this that I kinda like it on a normal basis.
There for a while, I was addicted to the Powerade drinks. I was so hyped up on the sugar and couldn't sleep. I had serious withdrawals when I tried to stop drinking those!
