Ever since we started NTNP, I've been taking prenatal with DHA. I've been drinking more water, and at the slightest indication of a sore throat or anything sniffly, I eat raw garlic.

I usually get sick multiple times a year. Prolonged. But I haven't gotten sick since I started this regimen.

Do you think it's most due to:
a) increased water intake? I went from drinking one glass every 2-3 days, to drinking about 6 a day.
b) pre-natal vitamins
c) garlic

I'm aware it's likely the combination of all the above, but I can't help but wonder which is the most responsible.
