Don - if you have a good gram measuring scale, or can borrow one, 100ml of mms will weigh 122.4grams. That will help.
The lemon juice is only 10%, not the 50% of the 1:1 citric acid, so I'm guessing it was pretty weak. The dose needed is 5 drops of lemon juice to 1 drop of MMS.
Jim Humble is recommending that for those with cancer, if they want to do juice, to be sure it's juice they've made at home - seems there are a lot of juices out there that are interfering with the action of MMS.
He can actually use the MMS within 30 minutes of a meal - and I'd separate it from his meds 30 minutes also. Just be sure, if he's doing vitamins or supplements (even moringa) to do them 2 hours AFTER his last MMS for the day.
