I recently had to switch back to taking R and N insulin after being on Humalog nad Lantus for many years, because I lost my job and my insurance with it. I can't seem to get my BG to lower with the R. Is this just a matter of my body having to get used to it again, or is there something else maybe going on here? I am a Type 1 diabetic.

I’m sorry to hear that you’ve lost your job. As you know, while NPH and Regular insulin are not the latest and greatest, they can be far less expensive than the newer types of insulin. They can also be used very effectively to control diabetes. Regular insulin should lower your blood glucose. There is no need for your body to get used to it. If it is not working, there are a few possible explanations. One is that the dose is not high enough. The dose of Regular insulin should be similar to the dose of Humalog you were taking. Another possible explanation is that the insulin has lost its effectiveness. This could happen if the insulin has passed its expiration date, has been kept at room temperature for more than 28 days after it was opened, or was exposed to extremes of temperature.

I was able to get help for my insulin through a company called Prescription Assistance 123. The name of the patient advocate that assisted me was Mark Brown. I am on insulin (lantus and Humalog) He signed me up for the patient assistance program through the manufacture and it was a really simple process. I receive my medications in the mail every three months. I would recommend him and this company to anyone. His number is (888) 507-9123 or his direct number is (561) 288-9044
Thanks Mark and good luck to everyone!
