Am I GREAT?? No!!! Why??

Oh my god!! I don't believe this!! Its almost 2 at night, I was almost as asleep as dead when I wake up suddenly with a weird.. yup.. a very WEIRD thought up in my mind...that WHY THE HELL I DON'T DRINK?? Can u believe this??? 
I mean, what is it that I am trying to ask myself?? or probe?? or prove?? may be... 
Is it that i am some kind of NICE GUY here, who does all things right.. who thinks too much to NOT TO DRINK because that wouldn't be GOOD??? Do all of them who drink or smoke think that much about what they are doing?? Or is it just another thing that they do in life??
I mean its kind of strange!! Isn't it?? Does being a NON SMOKER and a NON DRINKER (I don't know if that word actually exists) make me better than others who do that stuff?? If yes, then how?? What is that they probably don't have that I have?? Or what is it that they loose and i save?? Going as per what is said, they loose valuable days of life, will get sick at some stage in life and will face serious medical consequences due to their habits... But is that actually the reason why I stay away from it?? May be not so exactly..
There are many things which can have adverse effects at some point in life but still most of us do these things.. don't we?? Even I keep doing certain things like over eating, less of physical work, improper sitting and standing postures, high calories and fat in diet, excess of watching TV and working on computer etc... But hey... all these things are not declared as social evils???.. whereas SMOKING and DRINKING are!!!
So, am I convinced here that I am a better person than all those in the world who drink or smoke??? Well, I don't actually know as yet!! I guess I need more probing, more introspection here... need to ask a few more questions to myself and find answers to them... but one thing I am sure about is that whatever the answers may be, i am always going to be a NON-SMOKER and a NON- DRINKER (I don't know what they call'em ;)..)
By the way, now since i am going to stop here to get back the bed; I really feel strange for what I am thinking and doing for last 30 mins.. I mean.. that's outrageous... How can I.... arggg..... forget it... bye... good night...
