Anyone out there switched from Synthroid to Armour. Been on 3 weeks, feel a pounding. Getting another TSH next week. Dr.said we may have to play with dosage. Any other thoughts? Tree Frog, you know a lot, what 's yout opinion? But I did lose 4 lbs. on it, in 3 weeks. So that's something. Thanks and see you on the new board. Happy HOlidays. GailD/
