Did you go through any training first? Who did it, a Dexcom rep or CDE from your endo's office? Or did you just figure it out on your own and start it with no training? I'm wondering because it seems very simple & straightforward. We live 230 miles from our endo's office and I'd like to avoid another trip over if I can help it. The Dexcom rep is also in that same town and doesn't travel this far. If we have to go through training we'll need to wait until September to start the dexcom and I'd rather start sooner if possible.
