Welcome to Healthcare magic,
Although your symptoms sound like those linked to hyperthyroidism
and hence requiring an adjustment of dosage, however since the TSH
(2.106) is well with in the range therefore another cause for such symptoms (heart palpitations, nervousness/anxiety
and hair loss should also be ruled out) i.e. Pheochromocytoma
should also be looked into.
For that a urine test by the name of 24 hour urine for metanephrines can be done.
So if that turns out to be normal then one can adjust the thyroxine
dosage. And when adjusting the dosage you do not need to go for complicated dosage pattern. Trying for dose in between the two doses may help in an easier and better manner.
