If all else fails Matt, you can get on a good thyroid support from your local healthfood store. Wait until after you see the endo though.
Don't give up if you have symptoms, because your TSH is out of the new American Endocrinologist lab range for TSH (0,3-3), but for most doctors 3.5 is not high enough, so they will ask to retest it in 5-6 weeks or 6 months (like my last ENDO ask for)
Well, I made an appointment to go see an endocrinologist who specializes in thyroid issues. If he tells me there's nothing wrong with me I think I'll just give up.
I have TSH 2,9, feel tired with that and some anxiety and insonnia, when I had TSH 3.5 I was really sick (couldn't do exercise, pannic attacks, etc). Because they are in the "normal" range still not medicated (and my TPO antibodies last time were 815, I have Hashimoto), keep testing every 4-5 weeks, it's what I am doing , doctors want to see how my TSH changes.
