Nice to meet you.
I wanted to let you know there is a great website and support group for people with MCS called The Canary Report. People there range from folks with just a slight intolerance to people who are filing for Disability because of MCS.
One thing I have discovered over the years is that some foods have chemicals that trigger my MCS, such as wheat grown in America that has been sprayed with bromine. That is just one example. Everyone has their own intolerance level. Mine is MOSTLY perfumes also. It has impacted my life in unimaginable ways; no church, no malls, no makeup. But in many ways, life is much simpler and more enjoyable. So there are gives and takes.
There is a lot of great information on the Canary Report pages. You might find it an interesting site to poke around. Here is a link. Hope to see you around.
