Sylvie has been ill since she was 9 years old and doctors are not very sure why. One doctor has said fibromyalgia, and another has said Mast Cell Activation Syndrome (MCAS). She said on her application form, “I think that this has impacted my life in a large way. This issue has caused me to not be able to partake in everyday activities, do little to no exercise on a weekly basis and it has prevented me from hanging out with friends as much as most people would.” Sylvie made a very fast recovery using The Switch. Here is an update from her one year later.
