Burritos with rice and beans and muffins? Whether you're at 140 or 200 after you eat, these are very high-carbohydrate meals foods that require more insulin than you have (or have access to). You're taxing your pancreas and, if you need to lose weight, you are doing yourself a disservice. Regardless of whether you fall into the pre-diabetic or diabetic range from a clinical standpoint, you know that you're diabetic. The meal plans are going to have to change. The fact that you can't count on being normal after eating the same meals should tell you something - namely, that you can't get away with them on a regular basis. You do appear to have caught diabetes fairly early and, because of that, a diet that restricts carbohydrates a bit more could have a profound effect on you and keep you off medication, potentially for a while.
