Can you suddenly stop taking your synthriod and go to a natural source from tcm and or iodine replacement?

See a professional Homeopath. As you notice improvement you'll be able to gradually cut back on the medication (not stop cold turkey) and observe results conservatively. Some people have been able to get off Synthroid altogether, however it depends on how well and if your natural thyroid function can be restored and boosted to peform normally. Homeopathy can also reduce the side-effects of conventional drugs in many instances.
