For tonight you can try a dose of Benedryl too. It always took a double dose for me, but that can really make some people sleepy, so be careful.
Alka seltzer gold is something that helps lots of people too.
Adding peroxide to the Epsom Salt baths helps a lot too.
Far-infrared sauna use is one of the best ways to detox toxins in the tissues, so if you have access to one, start using it slowly too.

Activated charcoal is something that bind the toxins - but it will also bind to everything else, so you have to keep it at least 2 hours away from food, liquids, and meds/supplements that you want your body to absorb. If you can find a 4 hour block of time where you aren't eating/drinking/taking meds - then take it in the middle of that - or just before you go to bed.
And realize that detoxing isn't something you do just when you feel bad. It's not very effective if you reserve it for that. You need to be detoxing daily, although you will have things that you only want to do every few days or once a week, depending on your body's reaction. We are here to help guide you as you find what works for you.
