I have been on levothyroxizine for quite a while, 125 mcgs. I was recently increased to 150 mcgs due to having bloodwork come back abnormal, and then after a month on 150mcgs dr bumped me up to 200 mcgs saying that my thyroid was even worse. Now, im so exhausted I cant get out of my own way, sweating alot, but mostly just tired and irritable. Whats going on? Why did I feel better on a lower dosage?
