Have been using Fiasp in Omnipod since 2019 . Initially worked within 15 minutes. Effectiveness now much slower 3-4 hours before BG reduces. Has anyone successfully changed back to Nova Rapid? I am about to try Nova rapid in Omnipod firstly in same / then different area to usual sites (although only 1 area left/ due to 56 years of injections )Unsure whether problem is effectiveness and or Pod sites.
