I have done the daytime flush twice. I don't get quite as nauseous because I haven't eaten all night. I drink my first Epsom Salt about 5 or 6 a.m. then the olive oil 8 or 9 a.m. I make sure I have had a couple BM before drinking OO. The results have been the same as night flush. I try to stay in bed 3 or 4 hrs. after drinking oil. The first daytime flush I did I just went about my regular schedule but I don't think it was as successful a flush.
