underactive thyroid
"My doctor and I tried every T4 medication out there, and although I felt better I still wasn't right.  After 2 years he switched me to Cytomel and I immediately knew I had found the solution.  All the hypo symptoms disappeared - constipation, depression, weight gain and exhaustion. My cholesterol dropped to 140... in fact, all my blood work is excellent.  It's very discouraging to know you're doing everything right - diet, exercise, sleep - and not only do your lab numbers not respond, but doctors tend to think you're not telling them the truth.  Finally found a doctor that believed me; finally found the right medication.  Life is good!"
