I'll try and keep this as simple as possible. I had Radio Iodine about 6 years ago as I had an over action Thyroid (even though I was over weight!!) I've been on Leyvothyroxine ever since as they killed off too much Thyroid and I became under active.
I've never been quite right on the Levo, getting headaches, tired eyes, aches and even Graves disease at one point. I'm taking 150mgs currently but feel lethargic and have started putting on weight despite a good diet and regular gym. I have very dry sore eyes and the lack of concentration and brain fog is not getting any better.
NHS say I'm in the normal range but I think my levels are low and I don't think I'm converting well so I had a private test done but not sure what the results mean in real terms.
TSH 1.26 mIU/L 0.27 - 4.2
Free Throxine 19.80 pmol/l 12.0 - 22.0
Free T3 3.7 pmol/L 3.1 - 6.8
Any pointers would be good, personally I think switching to a Natural based product would be better for me.
