If u dont know; change ur diet as much as you can, work to goin fully raw, im doing a 80-20 approach because i i love chicken nd fish, but no milk products, acidic foods, fake sugars, drink a whole lot of water everyday, take vitamins, try to be active, take the steps instead of the elevator, walk those blocks if u dont have anything better to do, no caffeine, no cigarettes! (<im fighting with that one)...Marijuana is OK (Medicine).
Now as far as the Environment Situation I've Worked i call centers for 15 year now office setting, we even have two screens now, i've noticed when this first start b4 other people we reacting 2-3 years ago , i use to get congested every day but only at work..hmm right?!?, I'm concerned we are a rare group of people who r being poisoned but this and our diet and a miriad of other things. I feel it causes a biochemical reaction wit what we eat and like a reverse far is puttion out a poisonous gas.. So what I'm wondering do all you guys work around computers 40 hrs a week for 15years or more?
