For any newly dx'd who are worried about people "looking at them" when they are doing normal T1 stuff in public, I am currently located in my local pub, libre had reached the end of it's 14.5 days (the 0.5 freebie is courtesy of xdrip+), so, took my jacket off, pulled the MiaoMiao off it, rubbed the sticky stuff off, attached new stickers, planted it on the 24 hr pre-soaked libre on the other arm, calibrated it with a bg test, and then took an injection for my next pint.
No-one batted an eye-lid. Although that was mainly because they were all staring at their phones...
