Hello John,
Hang in there …my pump nurse suggested to me , when I was so ready to pull the tubing out , because I was so frustrated : put the date on the calendar and look at again 2 weeks later …almost 8 years for me now. And you have 2 foreign things to deal with : pump and CGMS …how about trying to master the pump first and then look at the CGMS ? I don’t think I would have been able to handle both technologies at the same time. However everyone is different . Do you use the long or short tubing ?Would one be easier for you than the other?? You can safely touch the tubing without doing harm …just don’t let the cat chew on it, ha, ha !!
All the Best
