Excellent way of making CDS here - very easy, with photos -

read it through and then ask away - Charlotte has been doing the testing for you, but you can get testing strips if you want to "be sure" - Note that CDS has the smell, but not the taste of MMS.
Regarding the dosing with CDS - since it's so new, they're still finding out what works - will be honest. If you have a 3000ppm per liter mixture, then 1ml = 3 drops of MMS. I use a syringe without the needle - you can get one at the farm and pet store.
Some of the more recent work with CDS has indicated that higher doses are optimal for serious diseases - Andreas uses 10ml of 3000ppm CDS per dose for cancer - that's really a 30 drop equivalent - I know of others using similar dosing - maybe starting with 8ml and working up higher for cancer -
