Hi, I am on day 4 of a 5 day Water Fast and last night only go 2 1/2 hrs sleep due to the excruciating pain in my lower back, hips and legs. I had 3 warm baths with salts and magnesium oil which was good while i was in the bath but the pain quickly returned upon getting out. Finally this morning, after taking magnesium tablets and pink salt with no relief, i took 1/2 teaspoon bi-carb soda in water and the pain vanished...quite quickly. It returned several hours later, so i took 1 teaspoon of bi-carb with water and the pain vanished again. I felt so good i went shopping....the pain returned at the end of shopping so i took another teaspoon. It's 3 hrs later and i still feel good, so fingers crossed.
