I do not have a gallbladder ..and i have done 11 so far .. but no really big stones as of yet..so maybe only people with gallbladders get those. My advice to you since you have diabetes ..i am very familiar with it ..my son has type 1 diabetes ..is to possibly keep sugar levels up maybe while not eating during that 6 hour window before the liver flush...and just monitor yourself..I dont know what the other diabetics are doing..but possibly drinking a lil juice or something..the thing is you dont want all that food in your stomach before you do the olive oil/juice thing because you will VOMIT! thats why you gotta quit eating..but i am sure something easily digestible is fine ..like liquids or glucose tabs...etc etc..just keep a real close eye on yourself.
