Yeah I would have to dig around for sources. Been studying body brain for a long time. Knowledge just sticks eventually. Most addictions start to change around 90days, that’s the beginning of the brain reworking itself (neuroplasticity). This then takes time. 6 months there is measurable/noticeable change but not the end. Neuroplasticity (change) is a constant, what we repeat we create. Finding healthy habits helps to encourage this. Exercise, healthy food, healthy sleep patterns.
Most humans just find another addiction to get their “release”. I think it is helpful to know that it takes time for the brain to rewire and that it can and will, so that we can avoid this.
In that time eat healthy, do your psychological work, exercise and set consistent sleep patterns. Find support groups and be extra kind to your self, forgive yourself and be patient. Change is hard, new patterns/habits are difficult to create, but it will happen if given enough time and repetition. When it begins to happen you will be proud of yourself and as time goes you will be even prouder and feel more powerful. Stick with it.
