Thyroid experts - update and more questions

I have been on 25 micrograms of Thyroxin for a couple of months and I just had a thyroid panel run. I'll be discussing the results with my doctor next week, but how do these numbers look to you?

TSH: 1.5 (I know this is good: before treatment it was 4.0, 3.6 and 2.4)
T4 Free: 15.3
T3 Free: 5.2

Confusingly, I had the test on my anti-nuclear antibodies run again and it looks like they've disappeared! So maybe I haven't got an immune problem either?

I have to say, it's wierd how blood test results fluctuate. Just think how different the doctor's response would have been if my first FSH test had come in at 4.3 like the second one and not 46 like the first one. Just think if the antinuclear antibodies had not happened to be there the first time they were tested. At least I think I'm making some progress on the thyroid front, otherwise I feel just confused but on a higher level!
