Hi and welcome.
I hesitate to give any kind of advice on detoxing, everyone is so different. Please see a dr if for any reason you feel the need to, medical assistance might be a good idea.
She can and will get through this, usually alot of sleep helps and nutrition. I don't know the extent of her using and that plays a huge factor.
Be careful and stay close to her. And for you....be sure to take care of yourself too. If you have not already done so please check out our Naranon board here.
