lots of whyquit reading, sheer determination, too much coffee, advil for the headachs, cold water and coffee straws to chew, brush teeth immediately after meals, not allowing blood sugar to drop too much ( frequent light healthy snacks and meals) lots of cran and orange and grape juice the first few weeks
and the 100% belief the withdrawl would end, and peace would come.
IT DID, IT DID.
best of luck
