I would like to do that. So far there seems to be a huge difference in price if you buy the patches outright or have an insurance copay. They seem ridiculous price outright.

Wife and I got to try them at our friends in Bonaire. They stuck her and I (think it was a Libra free style). Hers lasted the two weeks and her blood glucose was almost flat with the way we eat low carb. Interestingly mine had a lot more variation around meals than hers but we ate the same meals. Mine never went very high but did vary a lot more within a range. But mine only lasted two or three days till it went kaput. I think I bumped it while taking a shower. They say if you accidentally move the sensor it will do that. I was disappointed.

We were diving every day and the scuba diving didn't seem to bother them. I was over 100 feet deep (three additional atmospheres of pressure or around 45 psi) and when I got back and dried off it recorded the whole hour time while under water on wife's phone (we did both sensors on her phone).

I think they would be great for anyone wanting to learn about their blood glucose. I have not pursued it as much as I could because I figure we are already eating low carb and probably would not change anything or at least much in the way we eat. 

If I tested diabetic my insurance would pay for one. But since I no longer test diabetic they will not. They even limited me on the number of glucose test strips they now will provide. I guess being healthy has its down side.********

For someone wanting to avoid becoming diabetic if they have elevated A1c and if they don't have a good understanding about carbs and sugar, a continuous glucose monitor would teach them about all they need to know within a few weeks. Doctor put my FIL on one. He will be 90 in a while. He didn't have a clue what was making his blood sugar go so high, even with us trying to help him. He knows now. Has caused him to cut out or back on a number of foods. He still struggles though. At 90 the mind is not quite as sharp as it was earlier in life. Kind of funny. His eyesight is so bad he can not see a phone readout. So his wife, my MIL, monitors him on her phone. She lets him know when his sugar is high and the phone lets her know as it beeps at her when out of range. About drove her crazy in the beginning till he changed some of what he was eating.

Continuous glucose monitors could change the shape of the way people view eating. They don't actually measure the glucose in the blood (but the space between the blood and the skin as I understand it) so they will get some funny readings in certain conditions. For example a hot shower will show a rise in glucose that it not really a rise in the blood glucose but just an increase flow of blood near the skin surface in the space the sensor monitors. That increased blood flow shows up as a slight rise in glucose.  So there are a few known things that will give false readings. But over all I think they work great. I would like to get one for wife and I.

I think there has been some push back against making them non-prescription. They are not going to be good for some food sales for the candy bar, snack food and drink industry. Maybe they will just raise the "normal" blood glucose range.********
