Clay is used to take a mold of a good tab. This good tab mold is fit to the broken tab, then filled with ABS cement. The tab is rough, and not exactly perfect. However, it is a full plastic repair of the missing section, and a great improvement over what was there.
The real reason we are feeling so run down is lack of nutrients in our soils. Even eating exceptionally well, we will still run short. Its a sad fact, but true. To cover those daily needs the best nutritionals out there can be found at http://healthforthesoul.youngevity.com/ My recommendation is the healthy start pack for your basics.
Weakness and run down feeling after eating. JSouth. I have an weird problem that I hope you can help me with. About 30 minutes to 1 hour after eating, I sometimes get this really weak feeling in the middle of my chest which is followed or accompanied by a run down feeling which I call the blahs. It's very similar to the feeling one gets after sitting too long in a hot bath but it seems to be centered in the middle of my chest.
