I'm glad she has found relief because I relate to her misery. My issues were completely tied to my diet- processed sugar which elevated the yeast in my body. I never had any testing as to this issue, but because I have eczema many suggest dietary changes. The yeast which live in our intestines, discharge waste though "leaky gut" issues that come with age. I had several complete neurological work ups, nothing was found. I never had external yeast issues. It took about 6 weeks giving up all sugar, processed and natural to realize this diet was making a difference. After 2 months the sensations stopped. Now 4 years later and no processed sugar and limited natural sugar I have zero issues, so no need for me to try the GABA. If the GABA stops helping her , she should consider a sugar detox to starve out the yeast. Also read The Yeast Connection Handbook by William Crooke, Md. Yeast is tied to many autoimmune diseases.
