Yuck, I'm sorry you can't convince her otherwise. I suppose the only possibility would be to get her hookd onto something else -which would actually help her, like keeping her too distracted by going to the gym etc. Maybe if she won't listen to you she might at least discuss it with a medical doctor first. Health is too serious to just mess with like that. I've read it can do real damage to your kidneys especially, but I'm not a doctor.
