That's interesting about temporary elevations in cholesterol. I'll wait a while before I get tested!

I did read some research that having carbs under 50 or calories under 1500 causes a rT3 problem. Maybe that's your cause? Its a shame to raise your carbs when you're doing so well, but maybe its time for maintenance levels anyway.

My dr had me on a very slow switch from armour to cytomel, over a year. I never lost any weight or got the benefits until I was on T3 only, I started losing weight right at 6 weeks off of all T4.

I hope this works for you. Keep us posted.
