My insulin Log

I am considering going to Taiwan for a year or two to teach English, and most employers offer the National Health Insurance. I am concerned about getting blood glucose testing supplies, insulin pumps supplies, and insulin. Clearly there is diabetes in Taiwan, but between the language barrier and trying to explain specifically what I need, it’s been difficult to get answers.
Basically, what I’m trying to find out is if it will cost me an arm and a leg to get my diabetes supplies with the National Health Insurance as well as where I can get what I need, including a doctor’s prescription.
Thank you so much for any info you can offer!
