In the beginning of his treatment with PZI and then Lantus insulin, Jake's numbers were much higher than 593 many, many times. So it is not unusual. But please keep checking for ketones. Jake developed DKA, and I almost lost him. The good news is that he has been in remission now for 8-1/2 months and is the healthiest he has been in years. God willing, he will be 19 May 1st.
