If I REALLY REALLY stick to my program, I can lose 2lbs a week. I did last week. I am happy with anything in the down direction, though.

I don't take natural supplements - I take a sythetic thyroxine (brand name Oroxine here in australia) - synthroid is similar. see my previous post for my dosages.

It IS possible, especially if you are optimally medicated. If you find you aren't losing and have other hypo symptoms (fatigue, cold, hair loss, etc) then see your doc again and get your meds adjusted.
