Horrible insomnia, at same time diagnosed with hypothyroidism and put on levothroxine (NO symptoms just a TSH of 12. Multiple cortisol tests inconclusive. AM blood cortisol high, 11 pm salivary normal. Failed dexamethasone challenge. Awaiting results of 24 hour urine. Endocrinologist seems puzzled. Am I being overmedicated for the thyroid? Since the insomnia started having night sweats 15 years AFTER menapause. Please help.
