How much would you need to drink? I seem to remember an episode of house where a character died from drinking tonic water. I've been having a few little cans every day, it's great to stop you reaching for the wine. It is not so nice that you swig it down, it's not sweet like coke, it's just something you sip out. however, been having a few every night and I couldn't get the answers I was looking for on google!
