Give yourself some time to become thoroughly fat-adapted, and then some more time for your blood work to improve. You might want to get tested at three months, but only if you can trust yourself not to freak out. Better to wait until you’ve been eating keto for six months to a year, to give your metabolism some time to normalize.
Be careful with your blood pressure medication. If you feel lightheaded or dizzy at all, it probably means you need to cut back. Are you working with your doctor to lower your prescriptions? If not, you probably should be.
Your doctor may not agree, but if I were taking insulin, I’d want to be off it completely. If you are doing this well without any injected insulin, then I suspect you can count on a further lowering of serum glucose as you continue eating keto. You will likely be able to dispense with the Glipizide too. Metformin is supposed to be safe to continue, but even there, you might want to have your doctor either reduce the dose or take you off it completely as your numbers improve.
If you are on a statin, consider getting your doctor to take you off it, since one of the known side effects is diabetes. You might even wish to consider refusing to take it, regardless of what your doctor says. What I have learned about statins so far makes me believe that they do very little good and can often be harmful. I should probably mention that I am not a doctor, so take my advice with caution and do your own research.
As you mention, it makes very little sense to treat an insulin-resistant patient with even more insulin. Good luck with your doctor, and I hope your wonderful progress on a keto diet continues. You are certainly doing great so far!
