Re water intake - I probably drink about 16 ounces of hot water all told with the 6 o'clock Epsom Salt drink. No more than that. The idea is not to dilute the Epsom Salts too much. Then, an hour later at 7, I'll have another glass of water to help with dehydration.
Ditto with 8-16 ounces at 8 o'clock with the 2nd Epsom Salt dose and another glass of water at 9. No more water that night. (You don't want to have water too close to the oil and GJuice - oil and water don't mix, lol)
