So I had labs done about 3 weeks ago. Here they are:
Ferritin, Serum: 71 ng/mL (30-400)
Triiodothyroine, Free, Serum: 2.7 pg/mL (2.0-4.4)
Thyroxine (T4), Free (Direct): 1.23 ng/dL (.82-1.77)
TSH: 4.470 uIU/mL (.450-4.500)
Reverse T3, Serum: 15.3 ng/dL (9.2-24.1)
Vitamin D, 25-Hydroxy: 38.9 ng/mL (30.0-100.0)
So, because my FT3/RT3 ratio is below 20, my doctor put me on 5 mcg of Cytomel, twice per day. I have been taking the first dose with breakfast, and the second dose about 5-7 hours later. The first day I took it, it was great. I felt amazing. I thought all my problems would be fixed in no time. However, about 5 days later I am consistently getting a bad response to the Cytomel. I get extremely irritable, tired, and sweaty. I feel awful. I feel like I could punch a wall. I would guess that my body temperature is dropping as well. It's been 16 hours since I took that 5 mcg dose, and I still feel lingering symptoms. So I suspected this was an adrenal insufficiency problem and I started to take Pregnenolone with the Cytomel. The pregnenolone definitely helped, but obviously not enough. Basically, I'm not sure what to do here. Around here, 5 mcg sounds like a larger dose, but I've seen other forums discuss taking 10, 12.5, 25 mcg at once. If I took that much I'd be in the ER. Should I cut it in quarters or halves and try just 1.25 or 2.5 mcg? Any advice would be greatly appreciated. I would love to know why I am so sensitive.
