Earlier quoted context omitted.
I did this for a while but got sick of withdrawal symptoms (my body seems to be hypersensitive in this regard), so I just stopped all together. Most recently cut out sugar. I feel so good now. I can't believe how many foods I was eating that had direct negative effects on my body.
You say "foods" - plural. Did you cut other things out besides sugar?
I've given up and started again on all of these multiple times to confirm each one. My body seems to have a sensitive withdrawal reaction. I notice symptoms if I eat most of those foods too regularly and then mess up the schedule, and a bad reaction if I stop all together within a day or so. I'm super curious about it medically but don't really have time to work with a doctor and learn why all these foods cause similar reactions. I'll just chalk it up to celiac.
Given other people's stuffy noses and bad digestion, I believe a lot of people have foods that are no good for them. I highly recommend elimination diets. The less I eat, the better I feel. I discovered decongestants a year or two ago, which makes life a lot more bearable when I mess up and eat the wrong thing, but I don't want to rely on that stuff to feel normal when I could just not eat the garbage I was eating.
