underactive thyroid
"I have been on dessicated Thyroid since I was diagnosed in 1999, recommended by my naturopath as superior to synthetic.  My problem has been that most doctors dose based on TSH which doesn't necessarily equate to thyroid function.  I was losing energy in the evening, falling asleep after meals and having a hard time losing some weight (not normal for me).  I found a practitioner to monitor dosing to my symptoms and I am much better.  I take 60mg in the morning and another 60mg in the afternoon and I have lots of energy and sleep when I want to.  I'm still taking less than many who regularly take thyroid meds, but I feel great."
