The drugs have basically made her totally dependent on the drugs and others around her. If she does not take the drugs, she feels pain all over her body especially liver area. Then she takes the drugs and feels bad that she did, so she does the LF. Her family is against LF. She is labeled as a psychotic by many doctors.
The reason I said no fast right now is first of all you want to find out what deficiencies you may have and build up the reserves and also as you said Ayurved says not to fast if you are a Vata type. Fasting is always helpful in one way or the other and we cannot predict what your body will work on first.
Please read Dr. Dean's book. It changed my life.
Hope whatever path you take helps you get over this hump.
