I have not had my dexcom very long and the sensor tape comes off or gets really itchy (so far in my 2 sensor experience)... but I have a couple questions since the sensors are insanely expensive for me and I would like to wear one as long as possible.
1. What "symptoms" does the sensor start to have when it is dying?
2. How do I get the stupid thing to stay stuck if I am still getting use out of it but the adhesive is getting itchy and non-sticky?
3. Do any of you long-term dexcom users notice scar tissue built up like with the pump sites?
