Thanks for the hint, Sandy! I'm going to look into Cytomel... I hadn't heard of that before either! I'm not sure of it's availability in Canada, but I'll ask my doctor about it. I know we talked about the T4 levels (he won't raise my Synthroid dose because he's afraid of the increased risk of osteoporosis). In the meantime, I've started the CLA and I'll let everyone know how it works.
