Male 56 Yrs Old, Exercise Daily 6'3'' 215 Lbs, Physically

Male 56 yrs old, exercise daily 6'3'' 215 lbs, physically and mentally I feel good. If used properly, is insulin Humalog / levemer routine the most metabolically and mortality / longevity effective means of treating type 2 diabetes. I have been on metformin for 10 yrs and insulin / metformin for the last 2 yrs.......a1c 5.8. I do experience severe lows periodically. I see many new oral medications on the market......I tried Januvia once, approx. 5 yrs ago.....side effects were horrible. Is there an oral drug that could possibly replace my current regiment and be safer for maintaining current a1c and better for overall longevity ???
