Don't worry about the change! You are getting a more consistent amount of the meds. When I think back...I did not take the time to shake the bottle all that much. No wonder we would have this low out of the blue! Thankfully, it was not to the detriment of my son's health. I think what has happened is no big surprise to the folks here. We switched to the pill in 1998 sometime. I will have to ask the endo out of curiosity! I am glad they finally saw the light. As for those of you who feel more confortable with liquid. Certain phamacists can make the suspension themselves. They make it from pills. You could check into that, but if you are not on a price managed insurance....it will be a pricey alternative.
