Lecithin may be the answer I was looking for according to http://www.drankh2o2.com


Here's what I found there:

Drinking hydrogen peroxide may cause an upset stomach. Hydrogen peroxide should be taken on an empty stomach, one hour before meals or three hours after meals. Food in the stomach may cause excess foaming, indigestion or vomiting. Those with chronic systemic Candidiasis may need to start with 1 drop in 8oz. of water 3 times a day, then 2 drops in 8oz. of water three times a day before starting a schedule. Do not mix chlorinated tap water with 35% Food Grade Hydrogen Peroxide! People with serious problems will benefit from staying on 25 drops three times a day for one to three weeks, then tapering down to 25 drops two times daily until the problem is resolved (1 to 6 months). Some patients take three or four lecithin capsules at the same time they take the hydrogen peroxide to stop the nausea.
