Hey Danny,
Just let go. Give in to the quit. Craves are uncomfortable but they won't kill you. Quitting this isn't much harder than rolling out of bed once you decide you really want to. Making that decision, with the intention to live by it, regardless of what future temptations and rationalizations come your way is the key.
Accept the fact this is going to suck until it doesn't. Understand that your going to be temporarily uncomfortable ( manic, insane, angry, irritable, sad, anxious). That is the price your going to pay to earn your freedom and perhaps save your life.
Temporary, but not fatal, physical and mental withdrawl pain, in exchange for your life. Seems like a no brainer from where I sit.
The easiest way to be successful is to READ all you can here. go to other resources and read it all. Then go to cancer and quitter stories and read it. Read each day until you find something to help you through that day. Then repeat tomorrow. You can do this. It is not impossible to quit. Put your fists up and lets get this done,
