Sounds a lot like problems I had with Candida Cleanse. I couldn't take that product, either. In fact, the cure was worse than the disease. Like every bad symptom I had with candida hit me at the same time. Awful. I quit taking it and just started taking one anti-fungal at a time, instead of the combination in the CC. For instance, I take caprylic acid for a few days, then switch to raw garlic, etc.
I've also heard that enemas are good to use to combat the die off effect, as it removes toxins faster.
