This sounds more like you are looking for some outside approval or rationalization to stop the fast. If you believed your accupuncturist or any of what you are trying to "rationalize" you would have never done the fast to begin with. Bottom line is if you wanna stop then stop. You don't need to rationalize or anybody's approval but your own.
There is plenty of info out there on fasting beginning right here in the forum with the Detox Stages in the FAQs from a book by Tom Mc Gregor called "Fasting to Freedom"
"Stage 4 (Day 16 to Day 30)
The body is completely adapted to the fasting process. There is more energy and clarity of mind. Cleansing periods can be short with many days of feeling good in between. There are days when the tongue is pink and the breath is fresh. The healing work of the organs is being completed. After the detoxification mechanisms have removed the causative agent or render it harmless, the body works at maximum capacity in tissue proliferation to replace damaged tissue. While a short fast will reduce the symptoms, a longer fast can completely heal. Homeostatic balance is at optimum levels. The lymphatic system is clean except for a rare discharge of mucus through the nose or throat. After day 20, the mind is affected. Heightened clarity and emotional balance are felt at this time. Memory and concentration improve."
