Sobriety can be hard in the beginning, but in time it becomes comfortable and eventually you can see your life, freedom and happiness return. It promises change.
Drinking/using will never change. If it's harming your life and your body, it'll continue to do so, repeatedly, with all the sickness, losses and emotional chaos.
A hard struggle with sobriety in the beginning is worth going through for what you gain on the other side. Stick to it and the grass does get greener.
