i have been hpothyroid for 11 months now,being treated with levothyroxine.this book has empowered me.a very easy read that you can understand,my doctor told me i was on the right dose of medication,but after reading this book i soon realised i was'nt,i went straight back to him and mentioned this book,he agreed to increase my dose and after a couple of months i feel so much better.as patients we have to remember that our doctor's can't just give out a magic pill and everything is going to be o.k. reading great books like this and becoming more knowledgeable of our own illnesses,and having a great doctor who listens goes along way,but most of all you have to learn to listen to what your body is telling you if you want to be in control and to live well.
