When we break the Water Fast with honey after day 16, because of really low blood pressure, would it be advisable to continue with the fasting for a few more days?

I know a case where the doctor was giving to the patient with gangrene, a sip of orange juice, each time her blood pressure was dropping too low; so that they can continue until the gangrene had disappeared.

Although I have this example, I would like to know what you have practiced.
