Contemplating 21 day water fasting

Dear everybody,

as I am writing this I am in pain. For over a year now I have been having GERD-related problems. For those of you who don't know, GERD is Gastro Esophageal Reflux Disease.

Basically, my esophagus muscle ring is not closing my stomach right and some of the acid flushes back. For a year now I am living walking zombie with zero energy. My throat is always sore and inflammed, I am having hot flashes and sweats and I can hardly breathe.

Part of the same problem is a small hiatus hernia.

I am desperate and very depressed. I am an otherwise healthy 30 year old ruined by this horrible thing.

Drugs are doing almost nothing for me and I am very seriously considering the 21-day water fasting.

I guess my question is whether any of you good people here has any idea if Water Fasting can help with this kind of problem.

thanks in advance
