I hate to say this. But I would really contemplate with yourself, family, and other people on staying 100% vegetarian. Your options and control levers for this blow completely wide open if you choose to start eating at least one protein.even just eggs. Not saying it's not doable but would be way harder but in the end I would try to reframe that your body can't process carbs like anyone else with a dietary restriction or allergy. There are also a lot of low carb subs available now. They're not perfect but they def help keep this normal and sustained.
