Thanks for everyone's help in the past and my results are looking good although since November I've been getting symptoms and weight gain again - had lost 2 stone since starting Levothyroxine but gained 8 lbs since!
I'm lucky my doctor is understanding and although little has changed on the Thyroid side has increased my dose by 25mg to 150mg and return in 8 weeks.
Free T4 22.2 (12.0-22.0) - this has come down was at 24.8 since last July
Free triodothyronine 5.2 (3.1-6.8) - lower
TSH 0.02 (0.27-4.2) - same
B12 573 (197-771) - a lot better since I've been taking B12 vitamins 500ug per day
Ferritin 76 (30-400) - I will try and get that higher - more liver on the way.
Vit D 84 (50.0-120.0) - this has leveled off since a 14 last year and now taking 25-50ug a day depending on the weather.
