Sorry to jump in late. I can see why you'd be fed up.... From what I understand though, your taste should return to normal 3 weeks to 3 months after chemo, so... There's hope yet. There's the Mediterranian diet, you could adjust that a little, maybe? (In some, they still push legumes and potatoes and the like, which aren't helpful for a diabetic) What do you still like to eat? Maybe there are alternatives that are low carb? For me, groceries have become less expensive because I don't usually buy overly-processed foods anymore, just make stuff from scratch as much as possible. I also buy a lot of freezer stuff, on sale. Also, if finances are an issue, you could just skip breakfast. It's called Intermittent Fasting, will do your HbA1c good too. Just have tea or a coffee (or a sugar free double espresso con pana, or an espresso macchiato?? Few carbs in that, but not much) You could even go OMAD (One Meal A Day), just make sure it's a good one that'll keep you going. A lot of us had to compensate for food restrictions due to other reasons, so you're certainly not alone. Thing is, to find work-arounds where possible.
Good luck,
Jo
