It absolutely is. Cut back the insulin and cover lightly. Your body will still sporadically produce insulin for some time. My honeymoon lasted almost 6 months and I usually ate extra snacks to cover lows in between regular meals.
Sorry about your recent diagnosis, hope we can help. Small moves on insulin and carbs, a lot of trial and error and continuous monitoring and you'll get the hang of what works for you before too long. Many people here are very happy to help, it's a good place to ask questions. Don't hesitate
