Hello dear patient, you are diagnosed with hypothyroid, so you need to take thyrox tablet,
TSH blood test has to be repeated after 3 to 4 weeks to decide if your dose need to be changed or not. Regarding amitryptiline it can cause sleepiness so you can stop that after consultation your doctor. Foods don't help much with hypothyroidism so I advise you to take balanced diet, take
vitamin d supplements and
calcium rich diet. In case you need a second opinion then you can follow up with me. Tc
