what do you mean pushing the pipe into your liver?
Do you mean funneling over your liver with the ozone output tube hooked up to it?
Drinking ozone water will only get so far into your bowels. Most of it is absorbed through the stomach lining, some makes it into the kidneys, upper intestine, and bladder.
To get to the lower intestine, you will have to do rectal insufalation. This requires an enema beforehand. Set the flow of the regulator at 1/32 lpm, and make sure the machine is generating less than 55 gamma.
