I have been using Tresiba for over a year now and I have not had any issues. Since I only use it once daily in the morning I rarely carry it with me. It stays on my night stand, unless I think weather will prevent me from coming home from work or something similar.
I know the NovoLog pen is...
I am only on my third sensor, but with the two that I have removed so far I had to use a lot of force. I my case I had to force the glue to detach between the sensor and the "sticky pad". Only once the sensor was detached could I remove the sticky pad from the skin.
I am planing to go for a SPA...
