I don't know when it started, but I no longer have withdrawal symptoms from many things.
I used to drink coffee every day to stay awake, and I don't feel any discomfort if I suddenly stop.
Sugar, which used to be the hardest to quit, and even carbs, are now easy to cut out.
I can also quit social media at any time, and I won't feel the urge to check or post for a month without doing so.
