I used to be a drug addict back in the day.
What were you addicted to at the time?
I used to smoke a lot of weed
It is good you got over your addiction. Drug addiction is not a joke, and many people suffer from it.
Sometimes it feels like the urges do come back.
If you feel the urges, maybe you can go to a rehab specialist to learn some tricks to stay off. Relapsing is common to those off addiction and help is there if you need it.
