You are in control, control of making the decision to quit....Its just unfortunate that some peoples genetic make up is allergic to alcohol..That is one is never enough its always over the top. The same way some people are react to nuts or whatever. The thing is we make up the population where our bodies crave, for alcohol. One drink sets a chain reaction. So to be in control one needs to accept their condition and do something because it will never change. Gud Luck, take it one day at a time
