Re: possible tapeworm infestation.
You might want to try Adrenergize. There are lots of good reviews of it at places like iherb and I love it & take it 2X a day.
If you are gluten intolerant then it may take some months for your intestinal villi to heal. As for candida, you can kill it in the colon with things like cheap hydrogen peroxide and apple cider vinegar (though they will cause die off so go slowly, maybe on non work days) in enema bags with about 2 cups of water per wash.
Kefir and yogurt will help get rid of candida and don't have to be any more expensive than milk. Simply take a glass of regular milk and a tablespoonful of either live yogurt (like nonfat Danon's) or live kefir and leave it sit for about 10 hours. You have eternal probiotics that way.
Kefir seems to be the most powerful, but then it also causes some serious die off so go slowly & cautiously if you use it.
Low enemas seem essential when killing lots of bugs.
Places like vitacost & iherb sell cheap
Wormwood /black walnut tinctures that are very effective at killing parasites.
I got rid of my bugs in about 3 months. Yes, you can get rid of them alright, but you have to do maintenance afterwards.
If you haven't seen it already, I have the story of how to get rid of
parasites & much else in the post below about "Possible whipworm infection."
