I heard of a few products like Sonne's #7, naicin, and blood and body cleanse pills from GNC and the blood and body pills from a health food store.
Try Sonne's #7 from GNC or Vitamin Shoppe I believe. I heard its effective and to take it the night before.
Drink plenty of water...plenty. Drink cranberry juice and if u can stand...drink teaspoons of vinegar. Shyt nasty but can help u clean. Also, detox urself with juicing veggies and fruits like carrots, beets, celery, kale, spinach, pineapple, oranges, lemon, ginger, etc.
Exercise regularly and sweat it out as much as u can.
Take penicillin pills if u can get them. Heard they will clean ur piss.
