I think you can learn a lot of good info from reading this link.

You'll notice in it that the most important consideration is not medication dosage and test results. The most important thing is whether you have symptoms or not. TSH is frequently suppressed like yours when taking a significant dose of thyroid meds. That does not automatically mean that you have become hyper. You are hyper only if you have hyper symptoms, caused by too much thyroid hormone.
If you will please do as Barb suggested and post any other thyroid test results and reference ranges, members can help interpret and advise further. If you have not been tested, other than TSH, that is not enough. TSH is a pituitary hormone that is affected by so many variables, that it is inadequate as a diagnostic. You really need to know the levels of the biologically active thyroid hormones which are free T3 and free T4 (not the same as total T3 and total T4).
I was diagnosed with Hashimoto's Thyroiditis. I'm on synthroid and I was taking .125 and it was increased to .150

What thyroid disease have you been diagnosed with? Hashimoto's Thyroiditis? What medication are you on? What dosage?
Do you have recent lab results you could post, along with the reference ranges for each test, since these vary from lab to lab, and must come from your own report.
