I was diagnosed with hypothyroidism in May of 2007 have been taking Synthroid for five months. The doctor has increased my dosage three times, starting with 50 mcg, then, 75, 88, and now 100. My initial test showed my TSH level at 72.708, my T4 at 3.2 and my Free Thyroxine at 1.0. My hemoglobin, hematocrit, total protein serum, alkaline phosphate, and my cholesterol were also slightly high. I take the Synthoid every morning but am suffering from terrible insomnia, fatigue (even when I think I get sleep), irritability, neck and shoulder pain, frequent and loose stools, and a very high appetite, as well as a strong craving for sweets. I never wake feeling rested and tend to "crash" hard by the afternoon. I am not overweight and never really have been, but no matter how much I exercise I cannot lose weight. (I would like to lose five pounds to be back to my pre-pregnancy weight). I had a baby one year ago. I recently had my levels tested again on September 5, 2007. These were the results: TSH: 0.652, T4: 7.1, T3: 38, and Free Thyroxine: 2.7. I feel like I am losing my mind and my doctor will not do anything further for me. I have tried chiropractic care and am currently seeing an acupuncturist. I am desperate for some relief. Do you recommend adding another hormone for T3 or could the Synthroid be too high, causing me to be hyperthyroid? Why am I feeling like this?
