I have a confession......

I gave up smoking in 2004 but six months ago, I started back up on the dreaded weed. Roll ups as I can't stand packet fags and now I am having trouble giving it up. Every day I say 'I will give up tomorrow' but tomorrow never comes. I don't smoke in the house, I stand outside the back door whatever the weather. I am disapointed in myself. I was so proud of myself for giving up for so long. I am a fool to myself. I started back up as I was going through a lot of stress and illness but the smoking actually aggravates my stomach problems ( bile reflux due to the hospital ballsing up my gallbladder operation). I am not a heavy duty smoker and the first fag of the day always makes me so dizzy and feeling like shit, so why do I do it and find giving up so difficult to do?
Answers on a postcard please!!!!!!!!!!!!!!
