I am on Levothyroxin, starting in 2005 at a dosage of 25, no improvement, then raised by increments of 25 and so here we are in 2015 and I finally self I ncreased my dosage to 150 from 100. Finally, better concentration, able to perform my job, not as much anxiety and mood swings and STILL have gone from Petite 2 to a size 16 -- I EAT LESS THAN MOST PEOPLE and no junk foods. Is it possible to actually get the thyroid under control. russellwrangler in VA
