I tried for years then bought a book called "Allen Carrs, easy way" and ive never smoked since...

I know how fooking hard it was though... grim... fookin grim... best of luck pal, it DOES get easier, but dont take a puff or the drug is back in your blood and the addiction is refuelled again!!
On the subject of cream cheese.. that stuff kicked me straight outa ketosis, we are all different you see and thats where the test strips are invaluable
Just stick with meat and eggs, its hard i know but hey, what fookin isnt?
If you want to snack, buy a cooked chicken and eat it with mayo... rockin
