My primary care Dr. then put me on 150 mcg of
Synthroid and 15 mcg of
cytomel per day. I ended up with WAY too much thyroid hormone in my system after 2 to 3 weeks (TSH 0.04). It was awful - rushing heart beat, couldn't concentrate or think, highly fatigued, hot all the time. As a result, once I figured it out it was the medication, I totally went off thyroid for 3 weeks to clean out my system.
