Hi all! Anyone else have this happen? I started on fish oil, cod liver oil to be exact, to see if it made any difference. It made a lot, but I got sick also. Cold-like symptoms plus a sore throat. But they abated after about a week. And I got really good results from the oil, but didn't like for how much Vit. A, so I stopped. Then I switched to pgfo, and got sick all over again! Same symptoms, everything. And again they abated in about a week. Then I started my son on pgfo. Same thing. He got sick within a few days to a week. Similar symptoms, but sick enough to stay home from school 2 days! His illness abated also, of course. I guess it's like they say about a cold- use ALL the treatments-Hot packs, Vit C., etc,- and it'll go away in 7 days. Leave it alone, and it'll go away in about a week. btw, i don't even mind the tast of cod liver oil, and it's not flavored or cut. Go figure!
