Hi Tony, I don't know anything about CGMs but we have just come back from a holiday in Goa and my daughter has a pump. We toyed with the idea of going back to MDI but then decided to use the pump which was a good choice as she could have fresh fruit and ice creams on the beach with no extra injections. We disconected the pump when she went in the sea but that was about it really, and she was in the sea a lot. Insulin regimens have to be adjusted to allow for the hotter weather but we soon had that sorted. Iwouldn't want her to go back to injecting now and neither would she, she loves her pump.
