I was diagnosed with diabetes type 2 in January 2014. Diet and cycling helped me to "revert" the condition. By July I was taken off the medicine, metformin. The doc said at the time, make sure you don't go cyvling without any food on your stomach, that's it. Of course you have to look after your feet, etc..... like you do even if you don't do cycling.
My sugar levels are normal now so I follow a normal life..... in saying that, I should be more careful with what I eat.... that is what got me here anyway.
