The first thing is make sure you are following the diet protocol that others on the forum use. If you dont get on a candida diet you can take all the anti-fungals and probiotics that you want but you wont get rid of it.
Are you sure you are feeling rough because of the candida or the low thyroid? I was diagnosed with hypo-thyroid about a month ago. I have eliminated most of the candida but still feel terrible due to low thyroid. My naturopath put me on Thyroid Support and iodine. My tests show my TSH is coming down on the natural stuff but I still feel bad. I get tremors/anxiety/low body temp and feel shaky all the time much like yourself.
If you have been on anti-fungals that long and you still arent seeing an improvement I would guess its your thyroid. How long have you been on the thyroid hormone? Ive heard of people feeling better in a week and others take 6 months before the hormones finally start working.
