i have hashimoto's. was told i should begin with medication (25 mcg) to get down my levels, especially considering i want to get pregnant in the near future. i'm debating between synthroid an armour. any experience with both and recommendations based on that? also, am i going to have to continually up my doses to where my own thyroid no longer functions? i prefer to stay at a low dosage. does taking medication slowly deteriorate my own thyroid? i worry about that.
