Please Help - Drank Diluted H202 by Mistake...

Can the experts please come in here - I have a bottle of diluted H202 - I had some out in a glass to warm up so that I could rinse my gums and teeth.

Well I totally forgot about it and was thirsty - grabbed the glass and drank about 14 oz of the stuff. I thought I was going to die - I quickly drank a lot of water hoping to further dilute it - but was getting sicker and sicker to my stomach.

I decided to induce vomiting and thus also get out all the food I had eaten - I vomited and vomited and have been laying down - I still feel a little queezey but do not know what to take - should I eat a bread type of product to absorb what's in there or what?

Please, please respond - I feel better but I just want to be sure that my stomach and intestines do not get harmed.
