First liver flush attempt failed miserably, help!

So my friend tried the Liver Flush for the first time on saturday.

He followed the protocol using Epsom Salts and lemon juice and olive oil (and 1 tbl of Ozonated olive oil), but he failed miserably. He slept for 1.5 hours and then couldn't lie down anymore, he had to sit up. It's now monday about 48 hours later and he still can't lie down without feeling severely nauseus. I know this is kinda vague but has anyone had an experience like this?
