You should have a TB blood (or TB skin test) if you: 1  have had frequent close contact with someone who has active TB disease, 2  have lived in a country where many people have TB, 3  work or live in a nursing home, clinic, hospital, prison, or homeless shelter, or.  have HIV infection or your immune system is not very strong.
Sugar does not make you hyper, what could be making people hyper is the chemicals or additives in the food! Sugar in it's natural state may give you a bit more energy but in no way should it make you hyper, if it does, you may have trouble processing sugars and need to go get tested.
One reason may be a rebound effect, where some people end up consuming more of an unhealthy type of food because of the misperception that because it's sugar-free it's healthy. Also, be cautious with sugar alcohols â including mannitol, sorbitol and xylitol. Sugar alcohols can increase your blood sugar level.
