That's super 1 week off the radioactive cancer sticks.
For me it was effortless, from day 1 I liked
vaping better than smoking.
You might want to check into higher nicotine liquids. 36mg is sold by many juice vendors and will satisfy cravings better.
I have a friend who just quit smoking and was vaping the weak 18mg liquids that came with his kit, and smoking at the same time. I gave him a bottle of 36mg juice that I make myself and he's off the cigs totally.
