Hi, I don't have a Thyroid it was removed due to Cancer 31 years ago. I was on Synthroid 2.0, a doctor reduced to 175, I had severe symptoms including weight gain 5 lbs a month, & this seemed to mess my entire system up. I became sensitive to many foods, headaches, face peeling, heart palpitations (I have always had when low), etc.
Finally, I was changed to Armour 240 with 5 Cytomil, finally felt better. Kaiser tried Synthroid 2.0, did not work, instant symptoms.
