Hi! I am thinking the gum is generally used to help people wean off cigarettes and is not meant to replace them. Right? It's no wonder, as you know, that when you start to feel withdrawal, you get right back to it. Are there no directions about quitting along with the gum?
I suggest you tell your doctor about it. Maybe there's some program or professional out there who can help you to get rid of the nicotine addiction once and for all.
Have you checked on the Internet about such programs? I would think you might find some scientific studies with a bit of searching. Best of luck in quitting the nicotine habit!
