What levels is he testing, wackyjacky? If it's only TSH or T4, then you may have an incomplete picture. T4 has to be converted to T3 to be usable, and some people have a problem with conversion. In the very least, I would talk to your docs about taking a combination, T3 and T4 drug. Of course, hypothyroidism is just one cause of fatigue. Has your doc explored other causes? Finally, I'd note that there is no one right level for everyone. It could be that you need to be closer to the low end of normal with respect to TSH (remember that the lower the TSH value, the less hypo someone is).
