I have a digital thermometer: I do under the tongue, usually, though if I get a reading that seems way off (since food, drink, sleeping with your mouth open, etc. can all affect the mouth temp), I'll do under the arm. In-ear would be more reliable, I suspect.
The thing about the low body temp is that it's not necessarily a sign of low thyroid - but it is a sign that something in the metabolism is not working the way it should. (Which often *is* thyroid, just that that's not the only possible option.)
On the temperature: the more common thing for hypothyroid is feeling cold, but apparently the feeling cold *and* hot in waves is not terribly uncommon. (I had bits of it: at the worst, I'd have two or three bouts of being so cold I was shivering for extended periods, but also one or two hot flashes - bad enough to wake me up from sleep, or just make me feel lousy.)
Stuff I'd look at besides checking vitamin D levels would be other thyroid tests: TSH is a starting plce, but it can't tell you how much T3 and T4 are in your system, or whether you're converting them efficiently. (This is one I know less about, because my test results there are fine, but if you read the About.com site, they have good explanations.)
