You aren't alone! I also think that drinking and smoking are far worse than some other addictions. I do tend to get easily addicted to almost anything. It sometimes feels like a game of whack-a-mole! I've spent a good deal of time in therapy which has helped. Mostly now I'm fairly quickly aware when I'm heading toward addiction to something and immediately work to find less harmful substitutes. One example for me: I love to read books. I can get totally absorbed in this but I see it as a comparatively harmless "addiction". For me, anything that produces a certain brain state is addictive. Reading books seems the the least harmful :-)
