I have recently started on T3 and I'm still titrating the dose - currently on 50mcg split as 37.5 (7.30am), 6.25 (11.30 am) and 6.25 (3.30pm). My basal temperature has twice got to 36.6 C after the first dose, but it quickly falls back so I assume that I'm under-medicated and have a way to go.
The problem is that even at this dose I tend to feel jittery and anxious (like mega-premenstrual tension) although my pulse isn't excessively high (70's to 80 at the most). BP is normal. I also have a near-permanent headache and simply don't feel right.
I am 85% recovered from "ME" (adrenal, thyroid, digestive, mitochondrial and toxins issues) and had been doing well ( and feeling much better) on Nutrithyroid (alongside a range of other supplements) but I couldn't get my basal temperature beyond 36 C, although my thyroid test results seemed normal (see below). I assumed that this meant I had some form of hormone resistance, hence the T3 as an alternative, but now I'm wondering. I took 3 NT per day, but when I tried to increase to 4/day I developed an ectopic heartbeat.
I can't decide whether I'm being a wimp with the T3 and just have to work through it, or whether these symptoms mean it's not right for me (maybe I need the slower release effect of NDT??) Any advice would be really appreciated!
I know my ferritin and transferrin results aren't yet optimal, but I'm supplementing with 210mg ferrous fumarate for that. (I assumed that the iron levels weren't sufficiently bad to account for my remaining hypo symptoms.)
Test results were as follows (February 2013):
TSH 0.46 (0.4-4.0)
FT4 14.8 (10-22) pmol/L
FT3 5.7 (2.8-6.5) pmol/L
rT3 0.41 (0.14 - 0.54) pmol/l
Cortisol 27.7 (21-41) nmol/L
(normal profile except the slot 4h after waking which was low 3.7 (5.0-9.0) nmol/L
DHEA 0.24 (0.2 - 0.7) nmol/L
Transferrin 2.8 (2.0 -3.6) g/L
Serum iron 20 (7-26) mcmol/L
B12 1067 (191-663) ng/L
Folate 20 (4.6-18.7) mcg/L
Vit D 170 (>50) nmol/L
