i wanted to share my updated chart with the recent lab test done last week, and it shows correlation between ft3 and TSH, when TSH is falling so is fT3.....and i have the T4/t3 ratio at 6 now, and i think 3.5 is the level where one would feel nice, it was my natural level before i started taking levothyroxin. my fT3 is fluctuating in 3-4.5 range...and i felt the best when it was above 4.5! this was at the beginning when i was on 60 mcg dose!....so my doc was clearly targeting only TSH, and run me up to 150 now (last 7 dots on the chart
i think ft3 levels are cruical to well being not so much TSH level, this is my experience.......
now i had the lowes ft3 ratios during the summer time....and when i chnaged my diet (gluten free, more fats protein then carbs)....could it be that this is becasue i have too much t4? so its converting to rt3, becasue i read during the summer time you dont need that much hormones as in the winter, and i felt benefits from diet chnage, no PMS , which is really very cool thing ...also when my fT3 is low i teek i have blood sugar issues as well, weird sense of beeing hungry, while i just ate
