Getting off it was difficult. I couldn't have done it without the amazing support of my government, despite it's rather draconian drug laws. I've been clean for three years now. The impetus for getting off of it were the cost (I was using 1.5 grams per day), the illegality (I didn't want to risk my future any more).
But, the key reason? I didn't want to take it any more. A well known fact among addict circles, is that there will come a time when you're done taking it. The problem is, unless you were lucky to live in a country like mine, doing so without the support of society when it is so stigmatized is supremely difficult. It's an interesting problem.
