you need air, you need water, you need food to nourish your body.
the only thing nicotine does is keep you from feeling the symptoms of withdrawl, nothing else.
get past this initial stuff, then learn what it does to your body, see what you have done in the past, and learn new routines, new ways, new thoughts to carry you into a clean future without this poison.
But you are here, you have made a decision, and that decision can be so powerful. Remember and honor why you have made it and you will do well.
I wish no hope as we do not hope here, but I will wish you well on your journey to rediscover yourself and learn new things on your way to being free from any plant.
