T4 and T3 - Synthroid and Cytomal

Healing
There is a very informative book called "Living Well with Hypothyroidism" which talks about the balance of T3 and T4 and not just limiting long term to Synthroid (T4). Many Thyroid cancer survivors are showing T3 depletion symptoms over time and the medical community is mixed about using any T3 at all.
I have decided to follow the lead of several individuals and medical professions and am beginning an added daily dose of .25mcg of Cytomel (T3) to augment whatever T3 is being produced naturally by my hypothalamus and other endocrine glands.
I will let you know how it goes, but would love to hear from anyone else who has gone down this path.
In Health,
