I feel so bad for you. I use ParaCleanse chinese herbs by Natures Sunshine products because I know it worked for my sister. It has to be done correctly or it doesnt kill them all off... It takes 3 boxes with a 10 day wait inbetween each box. The last time I did it I used 6 boxes. i do it 2 times per year in case I pick anything up.
I eat at least one or two cloves of garlic a day, and other spices. Search on the internet for natural cures for killing parasites and a lot will come up.
