I know what you mean about feeling like an alien at first! But it doesn't feel that way for too long... I'm on day 36 and I attempted to quit alcohol and cigarettes on the same day and that didn't last, I had to give in to the lesser of two evils, so I continued to smoke.
Don't give yourself too hard a time, continue with the sober life and cut back on the smokes gradually, I plan to cut down on the cigarettes once spring is on it's way. Anyway, if you roll your own they are (slightly) less bad for you then regular cigarettes.
Well done on 8 days also.
