As all have said before me; you CAN do it! The early days are hard for most of us ... really hard but I can tell you for sure, quitting never killed anyone whereas the alternative; well, you get the idea. Even better than improving your health is being free of having to do what your nico-addict brain tells you to do 24/7. Just thing of how great it will be when you don't have to leave a party or any other function just because you feel you have to go for a smoke. That never happens again once you quit.
So many other fabulous improvements to your life are just around the corner.
Give it your all @I can do it!!!!
