You should start off with the most obvious symptoms.
"I have low body temperature to the point where I am getting hypothermia while outside during spring at night. Driving my car during the cold without the heat on.
And I get hypothermia when I smoke cannabis.
I think the cannabis is saying "Hey your thyroid is asking for help"
My issue with supplementing Iodine is that I am losing a lot of weight. I weigh 135lbs and can't gain weight."
This might correct your hypothyroid over the course of a few months. If not, you need a GOOD doctor to prescribe natural thyroid hormone NOT synthroid. Use this link to find a good doctor. VITAL ! http://www.stopthethyroidmadness.com/site-map/
Doctors should base their prognosis on symptoms, not their stupid TSH testing.
PS) Judging from your message history, you are one sick dude. First things first, cure your thyroid problems because this is the basis for all of your body hormones & your metabolism. I suggest you start out by verifying my prognosis of severe iodine deficiency with this iodine test. Also get the fluoride & bromide test. ( Stop taking iodine 1 week before this test ) http://www.hakalalabs.com/testing.html
Let us know how the iodine test turned out.
Severe iodine deficiency means you are LOADED with the toxins bromide, fluoride & chlorine. Get familiar with the detox symptoms.
