I doubt if low blood sugar is an issue. Those are excellent numbers, nowhere near "low". If they are happening AFTER eating, adding some carbs could very likely make them go lower when your body responds to it. The less carbs you eat, the less your BG swings between low and high. Without the stress of incoming glucose to your bloodstream, your body - yes even our impaired systems as T2s - are able to maintain BG exactly where it should be.
Are you eating enough? I would look there first. There is no need for ANY carbohydrates to feel energetic and have the vitality you need, but you DO have to eat enough food. Have you ever checked how many calories (for lack of a better measure) you eat in a typical day?
Protein is essential for cell repair and some of it may be converted to glucose for the 5% of your cells which must have it. Other than that, the only substitute for carbs in terms of cellular energy (ATP) is good natural fats. If you cut carbs from your diet, it is essential to get enough of those to take their place (9g of carbs = 4g of fat).
