<<Disclaimer: Verify this information before applying it to your situation.>> I can't say enough about what a difference the diet & guaifenesin have made in my oldest son. Over a year ago, he was hostile, angry, hallucinating & hearing voices, in tremendous physical pain and failing all his college classes, depressed & lonely. What happened to our bright & beautiful boy? Honestly, a year ago my husband & I thought he would some day end up in a mental institution drugged up on major tranquilizers with minimum wage employees abusing him & changing his diapers. He was deteriorating steadily. When I put him on the strict HG diet, the hallucinations stopped and his focus & grades began to improve. He started soon after on guaifenesin for fibromyalgia & the muscle pain began to diminish. He began to notice that cheese consumption caused "wicked thoughts" & mood swings, so he eliminated all dairy. He has since been diagnosed celiac & now is strictly gluten free. Casien (milk protein), and gluten (wheat protein) are very similar when metabolized & can have especially toxic effects on the brain. Now that he's totally gluten free casien free (GFCF) he's happy, calm, well grounded in reality, affectionate and making good grades in college. He's got an active social life again & feels hopeful for his future for the first time in 2 1/2 years. I'm so thankful I found this information. To my family, the GFCF diet and guaifenesin are nothing short of a miraculous. My heart is full of gratitude & I'm happy. Big hugs to Dr. Paul St Amand, Dr. Kenneth Fine and all the wonderful people on this and the fibromyalgia listserves for saving my son's future! ~Valerie in Tacoma, WA guai 1/1/00 GFCF diet
