One blood test came back as TSH a bit low, and T4 a bit high.
At the time I wasn't sleeping well (about 2 - 5 hours a night.
And I'd lost about 4 stones in 4 months.
No wonder the GP thought I was hyper, on the 125 levo a day.
In fact - the sleeping issue got much better when well treated with Armour thyroid.
The weight loss was due to a Lipotrim diet - 425 calories a day for 7 months. Brought me down to BMI 25, from BMI 36 or so.
The blood test was taken an hour or two or three after taking the levo in the morning.
