My mom is ill with something but we don't know what it is and how to help her. She can't taste on half of her tongue and that side is white no matter how she brushes it with tooth paste. She has dizzy fits and can't stand for long without feeling weak. She can't taste salty foods only sweet. She can't eat much of anything or she throws up. At first her entire tongue was white and she couldn't taste anything then after a few a day sh could only taste on the sides of her mouth and then now she can taste only on one side of her mouth. If you know or have any idea of what is wrong with her and how to help please reply.

The best advice I can give would be to see a doctor about this. It might be necessary to get a referral to a neurologist.
