@pawnshopguy Hi I have a couple suggestions about dealing with diabetes in general and trying to save; I don't know about the best insurance or more money making though.
Tip 1: Everyone's body is different but I've been able to cut back on my intake of short term insulin by switching to a low carb ("keto"- esque if you will) diet. This reduces the amount of short term I have to take at each meal. I don't buy "keto" products, I use the money I save by not having to re-up on the short term to buy more eggs, Quinoa instead of rice. Basically google the keto equivalent or best option of the food. I make my own keto buns, etc etc.
I've been able to save on two prescriptions worth of short term insulin by doing this , increasing vegetables and regular exercise to control blood sugar levels.
Tip 2: Manufacture programs. If you are taking a name brand sometimes the manufacturer will send you coupons in the mail if you sign up using a program online.
I can't be too specific about this as they are all differ and hard to find sometimes which brings me to...
Tip 3: Walmart. Recently Walmart has rolled out insulin and it's much cheaper there. For some versions you don't need a prescription which saves on doctor bills/copay.
Let's say fantastically: if your body accepts it well- you can buy a vial at $20 with no drs note at Walmart and if you eat very low carb you might be able to get away with no short term insulin if you time your meals right or only eat once a day.
This can be $20 -$40 month for insulin after you are able to know how your body reacts to insulin and certain foods.
Honestly without a doctor it does suck and I've done a lot of damage to my body having to experiment with different insulins and timings plus the expense of all the blood testing supplies but in my experience it came down to knowing what I can eat and when.
TLDR:
Vegetables + meat or plants - bread and carbs = less insulin consumed = less money spent
Brand name insulin? Check the site for deals and coupons
Walmart. Can get a vial for $20 bucks.
Find your balance between insulin, timing, and food as quickly as you can to maximize savings.
Ps: price compare cgm to blood testing materials. Cgm will help you out a lot. If the price monthly will be around same I suggest a cgm cause you can sometimes find tricks to help them go longer without spending more and they will help you find the balance MUCH more quickly.
Hope any of this helps.
