Yes, how much has the husbandry changed from her taking care of it to you? You said that the snake seems healthy so if that is the case, skip feeding for a few weeks. At 1700 grams she will be quite fine. A healthy snake won't starve itself. After a few weeks start introducing food again. When doing so start offering live rats. A healthy snake that is hungry will rarely turn down a live rat so that might be a great start.
