This works, Benzene levels are down and with it B2 deficiency and that in just 4 days.
Several notable side effects of this are immediate hair re-growth (where it should be), noticeably better carbohydrate digestion and diminished (near zero) need for 5-HTTP.
So beside Benzene allowing flukes to hatch where they shouldn’t it breaks carb digestion, conversion to 5-http and by burning up small amounts of B2 it causes other Riboflavin deficiency symptoms, most notable for me is hair growth.
NOTE: I now switched to Hulda Clark recommendation of 100mg of Niacin + 400mg of Riboflavin before every meal. The niacin is required to eliminate wood/isopropyl alcohol.
