What would it take to be free from blood pressure medication?

A lower BP. Unless there are drastic changes in lifestyle (diet exercise, wt loss or use of alcohol or medications) meds for high BP are generally for life. You may get small reduction in BP with minor changes but they are usually not substantial enough to modify therapy. However, if you have wt to lose, exercise to start and a better diet to eat, there is no down side to getting with the program.
