Yep, 3 months. That's how often I see mine. He's just a mile away though, but I'd think a hour drive would be worth it. My Endo has some patients that live 100 miles away and see him every 3 months too.
Something to keep in mind, Type 1 or Type 2, the care of these two really are not that different. Use of insulin tends to be the biggest difference, but even that is less so more and more with better research showing the benefits.
