To all the people saying stop drinking:
It's not that easy to quit when addicted, alot of people don't take addiction seriously. It's not like he can just say to his brain, "nope no cold drinks for today or tomorrow". Your brain will give these urges that will slowly by slowly increase and in time you won't be able to resist. It's best to keep yourself preoccupied with activities and hobbies so that your mind will just ignore these urges. And no, addiction does not just apply for cigarettes and drugs, soft drink addiction is a real problem which i also have. No matter how hard I try to quit i just can't, also Roo afza/jama-shiri taste like shit compared to cold drinks (my opinion) and are not a suitable replacement. Unless you can find a suitable replacement for your cold drink intake, you're going to have to devolop some other method to quit or reduce the intake amount.
