Hello, Josh,As a fellow phcamarist, I became disillusioned with-low fat dieting for weight loss, and after being warned I was pre-diabetic, I realized there must be a better way, for me, and for the country. After several years of research and experimentation, I lost 60 pounds and ditched my statins and antihypertenstives. I follow a mostly vegetable, 1-2 protein portions daily, unrestricted natural fats regimen, lifting a few reps of heavy weights several times a week. I indulge with some non-GMO popcorn, flax meal baking (cocoa delivery system!), and kefir, berries and shredded coconut, whenever I want. I feel great, eating once a day in the late afternoon or evening- never hungry in between. Wow- seems to me the medico-pharma-industrial complex exists to keep customers. Your blog is inspirational to many I'm sure, and I was glad to come across a fellow Pharmer who saw the light! Nice recipes and links. As Paleo grows, I hope we can become a healthier country- before we are bankrupted. Wish you well getting the word out- and, of course, good health.

It's not effective for me, but it could be an incorrect dosage. My doctor refuses to order a T3 or T4 test. I have heard from many people that levothyroxine is not as effective as synthroid, another synthetic medication. My friend is having success with a combination of cytomel and synthroid. I have having terrible side effects from this medication including depression, hair loss, fatigue, and I am always cold. My PCP dismisses my concerns. I want to find a new PCP and endocrinologist, but it's hard to get motivated when feeling this bad and invalidated.

I have been on Levothyroxine for over 17 years. Over the years I have had changes made on the dosage because I never felt normal. My levels have also tested as normal. After seeing numerous physicians and specialists, I have still received no help. My marriage and family have suffered because of my terrible mood swings. I feel very bad for my husband and children who have endured this illness with me. I feel out of control of my life. My symptoms have included weight fluctuations, dry skin, hair loss and cold hands and feet. When my dosage was changed to .150 everything got even worse. I am so frustrated with everyone and every little thing! It seems like there should be more help for people in my situation, as I know others must suffer from the same symptoms as I do. Whatever I do to try and help my situation it does not improve and I wonder if there is a more serious underlying problem besides the thyroid such as the pituitary gland or even my brain. I cannot afford health insurance so I am not sure what else anyone can do as I feel as though I am just a test rat. The situation is ridiculous. I so exhausted from feeling helpless and need answers. I feel I deserve happiness and normalcy.
