It it normal to fight christian sins and temptations?

I spent years sinning: playing cards, playing dice, playing horse-racing on my phone, playing cock-fighting and ball sports other than stoolball, lawn bowls and football on my phone, smoking in public which is extremely difficult to avoid, masturbating, but now I have none of these temptations, no more sinning, and for a little while when you stop for the first time in years it's a little difficult but it becomes easy. Is that normal?
