Maple, The hose has an anti-bacterial filter in it, so when water or what ever is dispatched from it, its been sanitized.
Anne, sorry but possibly, most the time stomach flu last 7-10 days from the time you notice the symptoms, there is a thought that you normally have it several days before in which you are really contagious to others. The rest while you are contagious you know about it, and do what you can to cut it down. Stomach virus's are no different then the regular flu in regards to the time frame.
With some it lasts 5 to 7 days, with others its 7-10 days, usually the 10th day really insures that you are over it. There will be days when you are like "Hey I must be getting better" and then you start doing things that taxes your body and then your like "Crap thought I was getting better" thing is you were getting better with the rest but when you started to resume it took all the energy you built up and depleated it.
This is what worked for me, eat in small portions, soup is good for you but also so is small light solid food, through the day, nausa try dry toast or saltines, drink plenty of water, gatoraide, poweraide, orange juice, vitamins, ect. While rest is good, try to exercise some for about 15-30 mins aday to keep the blood flowing and build energy, then rest some more, try to get fresh air by opening a window that isn't directly on you.
By Day 8 it felt like it was pretty much gone, and by day 10 I was pretty much back to normal. I recommend also using something like
"Oust" its an air sanitizer to get rid of air born bacteria, and lysol for the rest, it will keep it from returning, along with opening the windows for a good airing. Otherwise you run the risk of recycling it and re-getting it again.
By the way the Chamber is all purified and magically creates healing so that you all can get back to Nick Mania.
