I have been put on Armour thyroid because my body was not producing T3, my doctor first put me on 2 gr and I had fluttering of my heart. Then I went down to l gr and by the second week I had horrible insonumia, now I am down to 1/2 gr and doing ok,but not able to lose weight on weight watchers. I have been on Levoxyl for about 10 years and my doctor said if I didn't use Armour I would not be able to lose weight. My question is I can't seem to find a middle ground with the Armour, is this normal. Also is Armour stronger than Levoxyl?
