Thanks, fellas, I'm going to continue to try to perfect the method for my body size, but will have to stop smoking for now. If anyone has any final suggestions, however, about where I could buy home testing products that will allow me to test my creatinine levels and the specific gravity of my urine, it would be much appreciated. Thanks again - and feel free to toke an extra one on my behalf - maybe the cannabis gods will transfer a bit of that extra euphoria my way... (ha)
