I take a multi-vitamin, drink a ton of Gatorade/water, and take a few pepto. In the morning I take some more pepto, another vitamin, and then an aspirin or ibuprofen later. Nausea is typically the worst symptom I experience, so I've found the pepto is a godsend, and btw Chaser actually works. Very similar to how Pepto will help you -- the charcoal will grab toxins and send them out.
The multi-vitamin is for everything you pissed out, as is the water/Gatorade for hydration. I also find that sleep is VERY necessary. Nothing works better than a good amount of sleep.
