From what I see, Humalog is one of the most expensive insulins on the market. Is it possible to get your doctor to prescribe something less expensive for you? Since I am not a doctor and I can't possibly give you good medical advice, I can only give you suggestions.

Also, I don't know if you have an attorney fighting for your SSDI or not, I do have a good link for you with good information about applying for SSDI. It helped me tremendously when I applied on my own without an attorney and was approved. This thread is from our sister site at NeuroTalk and even though it was started in 2011, the suggestions still apply today -

Don't start your claim unprepared!!! - NeuroTalk Support Groups

Within that forum, there are many other threads that you may find relevant to your situation.

I wish you all good things and hope you find a workable solution for yourself!
