Once my thyroid was removed( it takes about six months to completely disintegrate when you have radiation iodine pill), doc put me on my current dose and I was feeling/looking great after approx. 2 months. That was about 15 yrs ago and no problems have occured since.

Everyone is different. My thyroid was completely fk'd. Yours may not be severe and you may feel much better without my drama. When doc adjusts dosage, it takes about six weeks to see if that dose is right for you. Good luck.
