I think everything can be controlled...life is meant to be enjoyed and unless and untill you won't taste than it's not easy to understand the taste, pros and cons of it....I tasted few of the poisons...but never let these to get over me...I mean addiction...yes once I was addicted to some Indian snacks...but when I realised I am getting habitual to it, I stopped using it....even though it was kept in my cupboard....
Some people are more prone to addiction than others. I think we just need to be aware of the possibility of addiction and recognize it as soon as possible. It was good you recognized that you were starting to overindulge in those snacks.
