Re: [IPk] Continuous Glucose Monitoring

Hi Terry

Thanks so much for telling us about this.  I am so excited that it will help 
us all.  I had been reading about it in America but was finding it difficult 
to understand what this Guardian was although I realised it was not 
available here.  The site I have been using is: 

I have been having a lot of problems over the last weeks and this would be 
so much help in sorting out how things should be.  I am doing the 11 tests a 
day plus extra each hour or over 10s and quarter hourly for hypos.  We all 
did it when we began but I did not expect to be doing it now.  I am so 
tired.  I wish I had one of these.  Does it really matter that there is a 
difference between this reading and normal readings.  Surely, if we accepted 
different danger points there would be no trouble for the patient.
