Good news about the doctor: T3 med plus FT4 and FT3 tests.
How much Cytomel? Is that in addition to your 125 mcg of T4?
TSH moves in opposite directions from Free T4 and Free T3. Reducing meds would decrease FT4 and FT3, thus TSH would increase; however, TSH is affected by so many things that it doesn't even correlate well with either FT4 or FT3, much less with symptoms So TSH should never be used to determine medication dosage. A hypothyroid patient should be medicated adequate to relieve hypo symptoms, without creating any hyperthyroid symptoms. So symptom relief should be the only criterion for successful treatment, and FT4 and FT3 and their ratio are the best way to monitor progress with increasing doses of thyroid med.
It seems that most doctors want their patients to have a suppressed TSH after a thyroidectomy for cancer. This is reported to minimize the possibility of a recurrence. That works well for you since most people find that when taking adequate thyroid med, their TSH becomes suppressed anyway.

I just sent you a PM with info on some doctors. To access, just click on your name and then from your personal page, click on messages.
Good thyroid doctors don't need to be Endos. They just need to diagnose and treat as I explained. If you will tell us your location perhaps we can suggest a doctor that has been recommended by other thyroid patients.
Don't be concerned about TSH. TSH is affected by so many things that it varies by up to 70% over the entire day. When already taking thyroid meds it has very little use (except to doctors who use it erroneously to adjust med dosage).
Note in Rec. 5 on page 10 of the link I gave you, "If the diagnosis of hypothyroidism is confirmed, then thyroid hormone replacement should aim at eliminating the signs and symptoms of hypothyroidism without producing any signs or symptoms of thyroid hormone excess. " Also, in Rec. no. 6 on page 10, "Dosages should be adjusted according to symptoms first and FT4 and FT3 second. It is totally ineffective to dose a hypothyroid patient to just bring the TSH level within the reference range determined using group test data" 40,41, 51.
I suggest that you supplement with Vitamin D3 to raise your level above 50. I doubt that a B complex would be enough B12. You might consider supplementing with about 250-500 mcg of B12 daily. You don't mention ferritin. It is very important and needs to be at least 100.
High cholesterol is a common symptom of hypothyroidism.
Make sure you request Free T4 andFree T3. If you just sk for T3, you might get a Total T3 test, which is not nearly as revealing as a Free T3.
When you get test results and find your FT4 in the high end of the range, and your FT3 in the lower half of the range, you can talk with the doctor about having inadequate conversion of T4 to T3, and request that a source of T3 be added to your meds, while reducing your T4. FT4 is fine around mid-range.
How much selenium do you take? Selenium is one that can be a problem when level is too high.
Don't assume that the new Endo will be a good thyroid doctor. Many specialize in diabetes, not thyroid. Many of them think that diagnosis and treatment of thyroid issues is very easy. It is not. Many of them have the "Immaculate TSH Belief" and only pay attention to that, which is very wrong. If they test beyond TSH it is usually only Free T4 and then they use "Reference Range Endocrinology" and will tell you that a FT4 test that falls anywhere within the range is adequate. That is also very wrong. You might consider taking with you a copy of the link above and if you run into resistance from the Endo, give it to him and ask him to review and consider treating you clinically, by testing and adjusting Free T4 and Free T3 as needed to relieve hypothyroids symptoms, without being influenced by resultant TSH levels. Symptom relief should be all important, not just test results.
Hypothyroid patients taking thyroid med adequate to relieve symptoms frequently have a suppressed level of TSH. That does not mean hyperthyroidism, unless there are hyper symptoms due to excessive levels of Free T4 and Free T3. Free T3 is the thyroid hormone used by all the cells of the body, so it is important to know. You have not even been tested for Free T3, so you do not know if your body was/is adequately converting the T4 to T3.
A good thyroid doctor will treat a hypothyroid patient clinically, by testing and adjusting Free T4 and Free T3 as needed to relieve symptoms, without being influenced by resultant TSH levels. Symptom relief should be all important, not just test results, and especially not TSH results when taking thyroid med. You can read about this in the following link. I highly recommend reading at least the first two pages, and more, if you want to get into the discussion and scientific evidence for all that is recommended.

In the paper on page 13, note rec. 10. "It should be noted that when taking adequate thyroid medication, the TSH level in an L-T4 treated patient is frequently suppressed below the reference range 79 - 81 . A suppressed TSH level means that the patient has become hyperthyroid only if there are hyper symptoms due to excessive levels of FT4 and FT3."
So I would definitely say you are hypothyroid, not hyperthyroid. You also need to get the doctor to test for both Free T4 and Free T3 every time you go in for tests. Since hypothyroid patients are so frequently deficient in Vitamin D, B12 and ferritin, you need to get those tested and then supplement as needed to optimize. D should be at least 50 ng/mL, B12 in the upper end of its range, and ferritin should be at least 100.
If you doctor resists doing these tests and is unwilling to treat you clinically as described, then you will need to find a good thyroid doctor that will do so.
