Word expression to say “Stopped smoking” or “got rid of some unhealthy habit”

Question

I'm looking for words ( or word groups) that can be used to say "I stopped smoking", or "I stopped taking drugs" or, in other words, "I got rid of some bad and unhealthy habit".

I have found "relinquish" , "get out" , "give over", but I'm not sure if they can be used that way. Of course, I'd like to see more examples, if they are present.

Answer 1

Kick the habit or kick the XXX habit where XXX is a suitable descriptor of the type of habit.

Answer 2

The easiest thing to say is "I quit smoking"

also

Answer 3

If you want to add some emphasis to the statement that describes your pride in the effort, you can go with, "I finally conquered my nicotine addiction!" or "I got the caffeine monkey off my back!"
