Minnie,

What was your TSH level before radiation and what is it now? You definitely sound like you should be on a higher dose. My normal TSH is 2.5. If it goes up to 3.4, which is well within the normal range, I start gaining weight and feeling tired, so it is important the know this number. Problem is at 3.4, my dr looks at test and says it's within normal range so thinks everything is great. I have him fax me results so I can monitor the tests myself. If I drop to 1.9, I also start having symptoms, but still within range. A simple little thing like taking the synthoid with calcium or a vitmain containing iron or calcium can reduce it's effectiveness. I started on 75, not enough, went to 100, too much, and now am on 88 which keeps me at my TSH at 2.5. I think the rule is take the thyroid med 2 hours before 6 hours after things containing calcium, iron etc. So get your numbers and take control and I'm certain you can get it back to YOUR normal.
