I'm pretty sure my now 2 weeks long bout of flu / sinus infection is nothing more than detox / die-off from the first 2 weeks of a Clarkia parasite cleanse (I'm 4 days into the third week, which is a "rest" week, and starting to recover). I've got some spirulina -- we'll see if it helps.
Also, I've finally eliminated 90+% of the refined sugar from my diet, which is raising heck with the candida, or so it seems.
When it first seemed like I was catching a flu bug I was REALLY disappointed.
2 folks around me (wife and a co-worker) have suffered the same symptoms (severe sore throat, followed by cough and congestion). I must assume it's a cold. I'm STILL not fully over it. So much for iodine, companion supplements, plus D3 limiting the length and severity of colds and flu. It's been over 2 years since my last cold or flu. I started D3 (5000 IU daily) about 2 and a half years ago. Iodine & companions about 5 months ago, so at least the D3 has helped with prevention...
