Here are some ideas..

Drink lots of water, eat apples all day. Green granny smith apples have high pectin, good for getting toxins out.

I read somewhere a while back that if you boil water for about 20 minutes it'll put on a negative charge which is also helpful for removing toxins, suppose to just carry them out.

If you have green field around, or maybe just your yard, as long as it hasn't had any chemical fertilizers or pesticides in quite some time... look around for dandelions and make a big dandelion salad. Just dandelions, maybe add some fresh chopped garlic.. it tastes good a tad bitter. It will help you a lot. Just use olive oil and apple cider vinegar, ideally, for dressing... add salt you may be lacking salt which might be why you are getting dizzy.
