I had plastic poisoning will mms help me?

Sure. The ClO2 will be liberated while the ice cubes melt in your stomach. Good idea

Every how many days am I supposed to increase my dosage, I took way too much and had way too strong herxheimer reaction again: mumbling and shaking but I know it is simply detoxification of plastic happening too fast as it (plastic) initiated it (mumbling, shaking).
I'm perfectly fine.

Is there schedule?

You will have to determine the dosage increase that your body can handle. If you are getting results, then you don't need to increase dosing. When you plateau, then increase again - SLOWLY. Good luck!
