Yup doing that today. Only off high dose biotin for 48 hours. According to my friend who has a thyroid issue and has asked the pharmacy this important question that’s enough. I didn’t have a choice my doctors office made this appointment fearing the worst. Again having NO symptoms of hyperthyroidism other than a high number on a blood test I’m pretty certain I’m fine but my doctor is covering his ass. If anything my symptoms are for hypothyroidism which the blood work didn’t show. Since this doctor is going to take these tests one step further maybe they could find an answer on the weight gain and the swelling in my legs. I figured it can’t hurt. Maybe they’ll see if I premenopausal or something. Another doctors visit. Sigh.
