just a post script to something harley said: note what happens "one hour later". if you eat something it takes an hour for it to the max affect on your blood sugar levels which in turn affects how well your meds work. (it just gets more complex everytime you turn around!!!!)
I would agree about journaling and keeping records. most don't amount to anything , but if your looking for answers, look for patterns. Then don"t forget to take your little notebook with you to the Dr.'s appointment.
