I only get sick once per yer. Well, at least that used to be the case.

I re-started Primal living in mid-January and since then I've been sick three times: twice with sinus congestion, and now I got diagnosed with inflamed bronchial tubes.

I'm flabbergasted at how I could possibly be getting this sick when I haven't been ill that often since I was about 10! I don't think it's "primal's fault" per se, but why is it coinciding so well with when I hopped on the bandwagon?

Is there any Primal-friendly ways to improve my immune system and increase my resistance to these things that keep ailing me?
