I want to quit drinking and smoking

I want to quit drinking and smoking, but the few days I'm successful at not doing either, or both, I end up failing to get sleep throughout the night until the wee hours of the morning, which guarantees I'll struggle with a sleep deficit throughout the day.

I don't subscribe to Alcohol Anomymous idealogy about alcoholism though.

But the thing is, I want to quit all that shit. I used to be brighter and wittier than I am currently, and that's biting considering despite having good grades throughout school, I no longer have the charm I used to have in social interactions.
