First thing, Its not easy.
Many times when I was trying to quit I gave in & had a doobie.
When & if that happens dont worry, tell yourself its not the end of the world (coz it aint). Dont be hard on yourself but remember your mind contains stronger will than your body & you can overcome. Just observe yourself when you are high, ask yourself if this is really what you want, It will strengthen your desire to quit.
Its true that you have to make changes in your life other than simply not smoking, Im sorry to say I lost
all of my friends when I quit. I couldnt spend hours sitting around in a room full of stoners while trying to quit. Maybe spend some cash on a treat (something you really want that will take up your free time) I found other things to do, reading, games, Tfp might be a good one too
.
Also, & this might not be for everyone, I started reading about drugs - what they do & why. I found that educating myself was fulfiling & gave me an idea of what exactly happend when I was waterbagged & what made me want to smoke and not smoke at the same time
This is all I can think of right now,
I wish you the very best of luck & If I can do it you can too.
