Woke up with a stomach ache, diarrhea, headache, vomiting, and slight fever, why?

Your symptoms are typical virus symptoms or even food poisoning. Food poisoning symptoms usually lasts longer than just a day. You want to know how to prevent this in the future. You have to build your immune system up. Why did some people get a plague and others did not when they were exposed as well? Why do some people go years without getting the flu when others get it multiple times a year? It is because of their immune system. One has a great functioning immune system and the other does not. When you look up a website with all the medical studies published from around the world, you will find that there are 5716 studies done on oxidative stress and the immune system. What that tells me is that there has to be a correlation between oxidative stress and the immune system OR medical unversities and privite institutions would not use their own money to do these studies. That would be time and money wasted. So, what causes oxidative stress? Oxidative stress is caused by our cells when they burn calories, they give off free radicals like 300,000,000,000,000,000,000,000 per day, the air we breath, food we eat, the water we drink. All these cause free radicals that bombard our cells causing oxidative stress. It is like rusting from the inside out. Oxidative stress is known to cause more than 300 diseases! So we think that eating anti-oxidants will help, right? Well, anti-oxidants will consume 1 free radical then die, so 1 molecule of an anti-oxidant will consume 1 free radical. Do you think that will make a dent on the 300,000,000,000,000,000,000,000 free radicals produced in our bodies on a daily basis? I don't think so. If we can get the oxidative stress off of our cells, our bodies can heal themselves. Easy? Well, not until recently. I've known I needed to be cleansed on a cellular level but did not know how to do it until recently. I feel better and better every day in more ways than one. My digestion is better, my immune system is better, my gums are better and don't hurt any more, my eyesight is better and now I don't have to get a new prescription, my allergies are 75-85% better and now I can mow for hours without it making me sick and I am breezing through this very bad allergy season. I can eat protein more now, I sleep better, I have more energy, my nails are better and feel silky. You see, when your body cannot absorb nutrients even if you are eating healthy, it slowly affects your body. This is what is called aging. When you are sick, you produce more oxidative stress. When you exercise, you produce more oxidative stress. When you smoke, you produce more oxidative stress. TBARS in our blood are an indicator of how old we are and TBARS are an indicator of how much oxidative stress we have in our bodies. If you can get the oxidative stress under control you can get your immune system functioning better. Make sense? Our anti-aging enzymes that are in our cells when we were kids consumed up to 1 million free radicals per second. Yes, PER SECOND! That is what kept us young and our immune systems functioning to their highest degree. When we eat processed foods and sugar and junk foods, that hinders our immune system from functioning at its best. You've heard of SOD and catalase and gluthathione, haven't you? Those are anti-aging enzymes. They have been discovered in the last 40-45 years. They diminish in their capacity to function after our skeleton stops growing then the aging process starts. In other words, we get older as we age or we get older as we get older. Fortunately, there are lots of studies on oxidative stress. In fact, there are about 77,000 independent medical studies on oxidative stress. Even in the last 5 years great strides have been found to get oxidative stress under control on our bodies at the cellular level. But you will need to do the research.
