Yup have been on 25mgs pred...am weaning off now...down to 15 at the moment....in a strange twist of irony the prednisone has balanced out the first trimester lows that most type 1's get so the net increase in insulin dose has been zero....which is awesome...At the moment with me weaning off the pred and still being in that window of hypos I am actually taking less than pre pregnancy insulin doses.....this will swing the other way in the next month or so...but so far so good!!!
