My guess is you are under done. Make sure your vit D3, B, B12, Irons, Testosterone are OK first . Thyroid disease causes malabsorption of these and without you can not process Thyroid supplements. They just pile up in your body tissue and give you side effects. Once you get Vit and Testost sorted, start increasing your NDT slowly , an adult male needs about 2.0-3.5 grains and some days more if you work out doors play sport etc.
For me it was a combination of B12 and Testosterone that enabled me to take sufficient NDT to feel normal. I also use slow release NDT taking .5 grains 4-5 times perday. You take as much as you need each day - if I'm feeling cold I bump up the dose , if my feet and hands begin to tingle I slow it down. This will amazingly get you good TSH numbers.
If you are a female - sorry I cant tell - but I imagine you still check Testosterone but also check oestrogen etc.
Hope this helps
