I know what u mean, and it is similar to the effects of alcohol. It is a fantastic short fix, but ultimately it does more long term damage. I know too many people who have ended up paranoid and/or psychotic because of it. I am not judging anyone, I'm only saying it coz I care. I can't talk as I have issues with alcohol and smoking for the same reasons, and I have to say they are such an easy 'quick fix' and not so easy to stop!...Oh the joys, we can't seem to win!
