ok, i'm not 100% sure i'm following you, but i like how you explained things...

i have been on the same dose i'm at for a very long time, i alternate 137/150's. everytime i try 150's everyday i get these dizzy spells where i literally feel like i got hit with a brick and the world spins, sometimes for several minutes straight and then i stay slightly dizzy for hours. since i am the only driver in my family, i can't risk it. also the heart palpitations are BAD!
my TSH was at almost 6 last test, which was a few weeks ago, and now i feel MUCH worse, so i'm guessing if i was re-tested it would be higher.. i can feel when things are wrong, i'm sure you know what i mean.
i'm also in a family of thyroid cancer patients and that scares the heck outta me!
