[QUOTE="Stroudie, post: 1608932, member: 117960"] Hi Peter Been reading your experiences about Freestyle Libre with interest and have the following comments as a Dexcom G5 user. The G5 for those who have not come across it before is similar the the Freestyle in that it has a sensor reading the interstitial fluid but it sends a blue tooth signal to your phone every five minutes. This builds up to form a graph of you blood glucose (BG). Moreover it signals alarms when you go high or low - no more coming to in the middle of the night with a paramedic leaning over you! (I am type 1). The dexcom like Peter's experience has been a revelation. I no longer inject my insulin 10 to 15 minutes before meals but 30 to 50 minutes according to my BG level and now rarely get post meal highs. I have learned that nothing to do with my eating patterns affects my dawn phenomenon (DP). Typically from around 4.30 am my BG rises from say 6 to 9 mmoll/l by 8.00 am. The only thing that fixes it is insulin. It is 35 years since I used metformin so I do not know how you take it but I suggest if you are trying avoid DP you need to go down the medicine route rather than the food path. As with FL the first 24 hours of the sensor is the least reliable and I am experimenting with putting the next one on before the current one expires. dexcom sensors count down after 7 days but if you shut them down wait a couple of minutes and re-boot it a further 7 days or so can be obtained. I do not know if this would work with FL. Dexcom users have to calibrate twice a day so an accurate finger stick machine is important. According to several web sites the most accurate is the Contour Next. The measure of accuracy is MARD (Mean Absolute Relative Difference). The Next has a MARD of about 5, while both FL and dexcom are about 11. This information is about a couple of years old so might have changed. Many other meters are above 20 so not accurate at all. With regard to keeping them stuck for 14 days once I have put the sensor on I cut up strips of adhesive medical tape and put them over the edges of the sensor tape. Sometimes these fail but I just replace them. Not tried skin tac or had any rashes. The big problem with dexcom is that it costs about £3600 per annum although over £1000 less if you re-boot the sensors [/QUOTE]
