Be healthy for three straight months

I have been sick so many times this year it’s not even funny any more. I’m not like sick that I have to see a doctor immediately. But it’s just general feeling crappy. I will have sinus problems or my thought will hurt for about a week until it get’s worse and I HAVE to go see a doctor. So I’ll try and eat right; No drinking; no smoking whatsoever (over a month now!!), getting outdoors more etc.. Let’s hope it works! I’ll obviously only start when I’m feeling better!
