Lemon Juice!!! I know - makes me pucker too lol! Go out and buy a plastic lemon that carries lemon juice and carry it with you for a long time while quitting. When you get that terrible urge to smoke - have a squirt of lemon juice instead. The Vitamin C and the sourness will help with the craving!
We all know how we just crave that morning cigarette! Instead: Pour yourself a glass of cold water and add some fresh squeezed lemon juice or add the lemon juice from the bottle and drink it down! This will help with the cravings and its good for you too!
I hope it works for you - worked for me most days.
