I have a small nodule on my thyroid and, although my blood tests were just inside normal range, my doctor and I have been experimenting with dosages of Synthroid for about 6 months.
After 6 weeks on .05 mg my levels were lower than with no medication (TSH: .46, T4: 10, T3 2.8), so we doubled the dose to .10 mg. 6 weeks later I felt MUCH better, if a little tense - my levels were to TSH: .03, T4: 17 and T3: 4.0.
But we upped the dosage to .112 mg, since I wanted to see how I would feel in the high normal range. I couldn't sleep, so we have now lowered it to .088. AND, I stopped taking 350 mg of calcium citrate in the morning when I learned it could interfere.
I still feel more vaguely anxious much of the time.
I also take natural hormones for menopause - Triest (.675 twice a day - more used to feel like too much) and natural progesterone.
I started to gain weight around the middle once we doubled the dosage which I cannot control with diet or exercise. (I am craving sweets.)
Is this an estrogen issue or a cortisol issue or should does it sound like we should lower the synthroid dosage further?
