I am looking to get best diabetes medicine someone tell me about it?
Welcome to the forum, that's a very broad question that requires some clarification, mostly importantly type I or type II?
When it comes to best medicine, that's really for a medically qualified person to tell you.
However, you will notice that many forum members have successfully managed to have better control of their type II diabetes just by changing their diet to exclude carbs. Avoiding bread, pasta, rice and potato is a good place to start whether it's just one, two, three or all of those. Key thing being to monitor your BG to see what the effect is.
