Your doctor has doubled your dose instantly of thyroid hormones by 100mcg equivalent of T4 (25mcg of T3) when the usual increases are 25mcg levo every six weeks.
I am not medically qualified but would add 1/4 tablet T3 to levo every 4 weeks as you already take levothyroxine.
The fact that your body is telling you that something's not quite right, you have to recognise that it could have been too quick an increase overall within a few weeks.
Also the best way to should judge if a dose suits us is 'how we feel'.
This is an explanation of T3 also known as liothyronine.
You may be overmedicated. 25mcg T3 is equivalent to 75mcg Levothyroxine which is almost double your original dose. You should have a thyroid function and FT3 test to check. Please be aware that T3 is not a weightloss pill and being overmedicated can make people gain weight. thyroid.about.com/od/thyroi...
