I started my caprylic pill a week ago and am slowly increasing them as the time goes on. Physically I feel about the same but the last few days I feel really, really low and down and depressed.

Is this a symptom of the die off?

Yes. Have you tried the oregao oil for the candida? There's a long thread about it's efficacy in the Supplements and Nutrition forum.

Where can I find it?

And what other symptoms might I get?

I'm on oil of oregano, psyllium husks, and acidophilus and I get really sleepy after I take the oil of oregano, and I am depressed because my belly is huge and yet I'm eating low carb and have not lost a thing except water weight. I am determined to beat the yeast and lose the weight, and you hang in there. There are some really gross pictures on the web of the yeasty beasties. If you just picture food you are craving turning into that inside you, well, it curbs my urges! Good Luck!
