I have been a Type II for about 17 yr. No meds. Lots of exercise. Last Ha1c was 5.7. I hope you continue with your bicycling. I can't tell you there is a silver bullet to make your diabetes go away, but I can let others know that it can be controlled with a modified lifestyle if the changes are made when diagnosed early.
For me bicycling is the best exercise. I enjoy it much more than gyms. I was never a proficient swimmer, and I dislike running.
