As one who used
things to feel better, etc......for too many years, I can say now with almost two decades of nothing more than maybe two cups a coffee in the morning, I feel so much better not putting things into my body to
feel better/relax/chill, or whatever.....
You can use your mind as a tool, to induce your emotions, moods, attitudes, in such ways that you do
not need stimulates, etc, to feel better, etc.
Some of the stuff like yoga, etc, are wonderful natural releases....
It won't come overnight, but it will come, if you persevere!
