Hello Isabel, what you need to do, is do the research, go to whyquit.com and also be sure and look at all the info on the beginning of this web site. It helps make it all clear on why we need to quit finally. Then once you realize that you really need to do this. Please hang out here. This site is so wonderful, all of the people on here have been so much help with me quitting successfully. I just hit the 30 day mark and I know in a big part it is because of this web-site and everyone on it. i am rambling time to go to sleep. good luck and just remember you can do it!!!!
