Definitely flush now. Traditional medicine believes elevated liver enzymes are indicative of blocked gall ducts.
I had blood work done while taking large doses of MSM and detoxing. My enzyme levels were elevated. My doc said, "might be a blocked gall duct", and suggested I take the test again in a couple week.
I didn't tell her that I was taking 5000 mg of MSM twice per day, with 3000 mg of vitamin C. A week before the next test, I stopped the MSM and my enzyme levels were normal. I resumed the msm until I felt I'd finished all the detoxing it would do. I now take about 1 gram per day, with emergen-c. My enzyme levels are normal now.
