I agree with Atriana--Start a journal and list what you are eating and drinking--also what medications you are on. Meds can sometimes slow weight loss. Have you read Dr. Atkins book?? He addresses medications that interfere with or slow weight loss. My doctor did a t3 and t4 to check my thyroid but only when he did a TSH---(thyroid stimulatin hormone) did he find that I needed a small dose of thyroid medicine. Hang in there and don't give up!!!
