depression from candida treatments?!

Hi. I have been taking caprilic acid (which also has pau'darco root), garlic and milk thistle and dandilion for just over a week. Suddenly, within the last couple of days I have been majorly depressed. I am wondering if anyone knows anything about such side effects with these herbal remedies.
Secondly: for the first week of taking the supplements I felt a little queasy but I had a normal appetite and was able to stay away from Sugar fairly easily...I was so happy! Then, 2 days ago I had insane cravings for sugar. I even had a dream about chocolate cake! I am wondering if this is what's known as a "flare up"? If someone could please explain what a flare up is and if Sugar cravings naturally do get worse before getting better...? I don't know? Any info would be MUCH appreciated. Thanx
