I was diagnosed with Hashimoto's several years ago. I noticed a difference in my energy level within a few weeks of starting my medication. I gradually dropped all the weight I had packed on over the course of 2 years within the first year of starting my treatment.

I average about 500 mile each month on my bike and until recently taught full-time and moonlighted at a small animal clinic (I quit this job a couple of weeks ago ) after school and on weekends. I am tried but it is a normal fatigue not the debilitating fatigue I suffered when my thyroid took a hike. I was and continue to be amazed at how that little pill I take each morning has changed my life for the better.

The key is to make sure you take your medication at the same time each day on an empty stomach. I typically take my pill when I first get up, around 5:30and I do not eat breakfast until around 7:30 so that the medication has time to be absorbed in my GI tract. Also, it is important to avoid calcium/dairy products for two hours before or after you take your medication.

Good luck with your tests.
