Pixie--Thank you for your response. I am just curious how many people actually have problems with natural thyroid since the docs seem so set against it. I also am on T4 only, and do not feel well. I don't feel really bad, just not well. I don't know if I am converting T4 properly. I have asked my doc about Armour but he says the dosage is "unreliable" and won't perscribe it. I had half my thyroid removed 2 years ago due to a suspicious nodule--fortunately no malignancy. My current doc is the ENT who did my thyroid surgery, a synthroid fan, and won't consider anything else. I think he is a terrific surgeon, but it's time to see someone else for on-going thyroid maintainence. I finally got an appointment with a top endo. in March, long wait for an appointment but he is highly recommended so I hope it's worth it. I am trying to learn as much as I can prior to seeing this new endo. I have heard nothing but positive things about threrapies other than synthroid, and am curious what the negative side is all about. I'm trying to gleen as much info from other thyroid patients as possible prior to seeing this new endo. Anyone else out there who has had problems with natural thyroid, or Thyrolar the synthetic T4/T3, please post. I need all the help I can get. Thanks to everyone for your support. I have gotten more good info. from this board than any other research!
