I don't know why your blood sugar is yo-yoing like that. It's sometimes normal for a diabetic to spike after eating a large meal that has too many carbs, but why you're also going down to 75 is a puzzle. If it were happening to me (knowing what I know now), I'd see an endocrinologist. Diabetics can lose weight like anyone else when they cut out the carbs and engage in regular exercise.
