Cookie, who is advising you? In my non-medical opinion you are hitting your body with active T3 at much too high a daily dose too quickly. Dr Toft supervised my addition of T3 to T4. My T4 was reduced by 50mcg for each 10mcg T3 added. You are reducing T4 by 50 mcg then taking 25mcg T3. This seems to me to be a rather high substitution rate, seemingly suddenly introduced, as it is 2.5 times greater than Dr T's substitution rate. I would say, slow down, buy a pill-splitter and balance the T4/T3 ratios less extremely and take about three weeks to get the T4/T3 ratios balanced, especially if you are older.

It might help to know I also take my T3 in 3 x 5mcg doses throughout the day to maintain a constant supply of T3 which has a much shorter half-life than T4, so any T3 taken is reckoned to be "used up" in 8 to 12 hours.

Thanx so much for your advice, will buy a pill cutter and half my dose of t3, after feeling so poorly for so long I just want to feel well, but I understand it can't be rushed, thanx again gill x

Hi Not sure how you started the T3, but best to start on the tiniest dose the first week, take before a blood test. This is the best policy for side effect from all medicines, except of course, cardiac etc and antibiotics.

Best wishes,

Jackie
