The amount you're taking is VERY little. 1-2 drops daily is just scratching the surface. I bet it has to do with the fact that your body has become more tolerant to the Miracle-Mineral-Supplement and rendering it less effective. Plus the fact that you eat regularly also will lessen the effects of just a 1-2 drop dose. I myself have started on my intense Miracle-Mineral-Supplement protocol of 15 drops 3 times a day - 3 days ago - and as of today, I can already feel my body accepting it more easily.
I would recommend you start doing more drops....try going up to 4-6 drops a day, see if it makes a difference.
