On day 16 of water fast and detoxing is harsh!

I am detoxing horribily right now and it is feels like it is almost too much to bear, but I am handing in there, anyone have any ideas what I can do to deal with that aching abdomen and nausouness.

I have been drinking water, but trying to not do so in large amounts because it makes me ill, and I did an enema, but I don't know how often how I can do that to stop the build up of toxants in my body during a fast.

I can't remember it being like this last time, but the last time I did a really long fast was the Lenten Season in 2006. The longest after that was just 28 days.

Any ideas?

Thank you.
