Hormone supplementation is a tedious process to get just right, and it never stays exactly in the same spot over the years. Radiated patients that have had their thyroid lost, are very different from the normal population in what is "normal". So doctors that are not really up to speed on this situation don't get that normal lab values do not always apply to us.

Once you up or decrease your dose of this, it can take a month or more for your body to respond to it and balance out. My first go at taking synthroid took 4 Rx changes before I started to feel right (not cold and lethargic). And waiting 60 days to be sure my body was leveled off at the new dose / each change, was a pain in the rear� I wanted to feel better NOW. But there is no way around the time issue. I hope Charm will chime in on this thread he has the most experience and knowledge of any of the posters about this whole situation. If he doesn't in the next day or so, look his name up in the search feature, and look at his past posts. He has explained it a couple of times to people.
