Well for me, my diet was never terrible to begin with so I guess you could say I was lucky to not have to make any huge changes there. Just added more fruit and vegetables. The more colors the better pretty much.
Quit smoking was a big deal as I smoked since I was about 13 yrs old (I'm 43).
Getting my ass moving was another big thing as I was very sedentary all of the time. So I walk everyday, and make choices like parking far from the store and walking ya know, simple stuff like that.
My prescriptions are basically lipitor, plavix, aspirin, metoprolol and lisinopril. Yep, I take a drug that has "lol" in it, heh.
