Got my latest blood results today. TSH 6.3 (down from 18 6 weeks ago, and 46.9 13 weeks ago). Free T4 is up to 14.9 (up from 13 6 weeks ago, and 6.3 13 weeks ago). Feeling good now, even though it is still on the underactive side (maybe it always has been!). Back in 3 months time for the next check. On a side note, my favourite nurse is retiring , she is the one who never has any trouble with my deep veins.
