Denied Life Insurance?

I applied for 30 yr term life insurance and was denied. I have ask for my records from the MIB and am awaiting them. I believe I was denied because 5 yrs ago my doctor thought I was addicted to Zanaxx. My current doctor prescribes me Zanaxx but in very little doses? I definately am not addicted but think that his thoughts have hampered my application. What can I do to get life insurance?
