I have a pump. When I went to a spa I just attach each time I came out of somewhere wet and tested my blood sugar. I had already decided that I know I would poss run slightly high but would not let it ruin my day. Regarding massages I never tell them as it has never made any difference to my levels, some places won't even do it if your diabetic, I once was told I could have a massage but they would not be able to apply any pressure, I did say well what's the point then. But I've had messages all over the place and never tell now. I had one in Mexico last week and the only thing that effected my levels were the cocktails lol
