Sorry it took me so long to reply I had quit a bit come up to take care of at home. Anyway I took was not typical with my MCS. I was told nobody has typical MCS. Everyone with it will have their own unique versions of it. It's your brain reacting to a elevated state of stress. MCS can start out with one thing it's reacting to and gradually take on others. What makes that happen is that when we start having more health issues it increases the stress then in turn your brain picks out more things to be afraid of. We are reacting emotionally at some level sending those signals to the brain and the brain gets stuck in that state thinking that's what it's supposed to do to help us out. It started for me with supplements, then as my body because more stress my digestion started to go and it moved to foods. Then it started on smells.
I would call the Carrick Brain center and see what their program involves. I would also think there would be an ongoing training or practice you would have to do to work on the thoughts. Every Time we have thoughts about our MCS it tells the brain to keep on it's current program. To break that cycle you have to start sending it the messaging with your thought and emotions that things are back to normal.
I worked a year and a half on my thoughts. I had to completely let go of every though and action that let my brain know I had MCS. I could not even use certain words. If you react to name of the foods you can't eat you change that or just don't think about it at all. I didn't even talk about my MCS at all or did any research on my health. I couldn't even let my brain start the thought. It was a lot of work but way worth it to get a normal life back. All the best to you and let me know if you need any other information or have questions. I have some processes I use now for my brain and I can send them to you.
