First Time Flusher! (help! :s)

I'm afraid. I admit it. I have the Epsom Salts and olive oil and I'm going to buy a grapefruit in the morning. (wanted it to be fresh) But I'm very nervous about it. Can anyone answer some questions?

Does it hurt? Are you miserable, and for how long? Does the stuff taste horrible(salt water and grapefruit olive oil sounds nasty!)?? Do you have stomach cramps?? How long does it last until the "flush" is over?

I just don't know if I can force myself to do it. But I'm going to try very hard because I think I really need it.

Thanks!
