Type 2 Diabetes Reversed

a family member who has diabetes type 2 has been taking MMS drops for 3 months and no longer takes insulin,he has successfully brought his blood sugars down between 7-9 mml daily from high 20ies for yrs. Now he’s worried that his blood sugars are too low and have been dropping to between 3.5 to 2.5 , dangerous levels. Hes only been taking 1 activated drop a day .He in turn eats what he can quickly to bring his sugars up. Does anyone have any experience in this area. Some suggest it’s pancreatic enzymes issue, any suggestions appreciated
