Thank you for connecting! Side effects for me are headache, stiff and swollen knees and fingers and less energy. Your post has alerted me to get my Synthroid dose checked. Reported Dexa readings are encouraging! Has anyone found a brand of calcium plus magnesium and D3 in a large enough dose of what we need to feed the Evenity so that I don't have to be a daily pill counter? Can't take calcium on Thyroid medication and by afternoon I can forget some of the doses.
