Is past extensive cocaine use and alcohol abuse treatable?

Try having her checked at a mental health clinic, she may be depressed, or have anxiety, or something treatable. Wellbutrin can break any habit, smoking, alchohol, it has some nasty side effects like it breaks every habit you ever had, you eat differen't foods, can't look at a cigarette, and have to relearn to love your loved ones, at least it was so with me, I only took it for 3 days, quit cigarettes for three years...bring her to a clinic and see if they can help her, is my suggestion. And make sure she eats healthy foods, taking vitamin c can help detoxify the nicotine of the cigarettes.
