Back when I was veg, I got sick several times a year. Every cold/flu stuck around for weeks eventually became bronchitis, sinusitis, laryngitis, or worse. I seriously caught everything and anything. I was the girl who got the weird ear infection or contagious skin rash - and when I went to the doctor, they'd take pictures and bring in all the nurses and interns to learn about it. I do not miss that.
Since going primal, I've caught only a couple of colds which clear up very quickly and do not progress into the infections of the past. I got tonsillitis once, that cleared up with coconut manna. Many times everyone around me has been sick, but I somehow manage to stay well (even being pregnant now - which they say makes you more succeptible).
Anyway, hang in there and you should see a lot of improvement.
