Hi Jeni,
I also take a teaspoon of powdered cinnamon with my breakfast cereal. I wasn't sure whether it was doing anything until I went to the States on holiday a couple of months ago and stopped taking it for a week. My sugar levels went up, then came back down when I got home and started taking it again.
If you follow the advice about taking Cis oils, you also need to ensure that you cut out all the harmful hydrogenated (trans-fat) oils from your diet. Not so easy over your side of the pond as all the big fast food outlets use trans-fat oils to prepare their food (MacDonalds, KFC, Dunkin all guilty!).
One thing to be wary of is the various "snake oil" treatments (like diamaxol). They do use all natural ingredients, are very expensive, and don't work - which is why diamaxol has been banned by the FDA. Unfortunately it is still sold because the manufacturer no longer claims it to be a drug so it falls outside FDA's control.
