Bad yeast infection since killing parasites?

I have been on the parasite herbs (along with zeolite with humic and fulvic acid) for about a week and have now. The last few days I have been dealing with a yeast infection. Taking stuff my ND gave me for it, but it isn't helping. My cravings for Sugar are off the charts as well. I know that die-off can cause flare up of issues, but can parasite die-off do this as well? Thanks.
