Wow what an eventful Christmas! I should say my BGs were all over the map this Christmas, persistently high. So, having said that, let me release my inner Grump:
- whoever said you needed to drop your basal (from 30 to 20?) because of one six hour drop from 19 to 13 is a idiot. Was that your DSN? Basal testing is meaningless unless it's in the normal range. At 19 you are renal dumping and the drop could be entirely explained by your kidneys, nothing to do with your basal. So in turn, this ill advised dropping of the basal could explain the whole problem. Could have caused it.
- A lot of other plausible explanations were suggested and investigated but in your shoes I would also have suspected an asymptomatic infection. That will drive BG up persistently and resistantly. And if your basal is inadequate that will make the infection worse, and harder to get rid of.
- I think it is jumping to conclusions to switch to Levemir or even to twice daily Lantus (even though I like that regime). First thing you should do is get back to the original Lantus dose, which *was working*, and see if it resumes working. Don't fix something until you first prove it's broken. Otherwise you are just adding a load of new variability to an already confusing situation.
I am really moved by the support everyone showed you, and also your really nice attitude in taking the advice graciously. Merry Christmas, one and all! xxx
