Major headache on Day 9?? Advice please.

So I planned to do the Master-Cleanse for 10 days. I did it for 10 days two years ago and everything went according to the book. Felt great by day 10.

Today is Day 9 for me.

This time, everything has been pretty good, gave up smoknig on Day 1, my face broke out severely and all the little pimples still have not cleared up, and my tongue is still kind of green....

But the biggest surprise is this massive headache. It began last night (so end of day 8) and it's gone all day today. My flushes have been pretty good, I've had the tea every night, SWF (Salt-Water-Flush) every morning... and I drank a lot of extra water today, but this headache is killing me.

My question is, even if the headache disappears tomorrow (day 10), should I still not end the Master-Cleanse after 10 days? Because I should be in the clear (feeling good that is) for a few more days before I end it, right? If I have a major headache on Day 9 that means I am in the middle of some serious de-toxing?

Argh.... I so wanted to end it after Day 10... but have come all this way so don't want to throw it away...

Advice and opinions welcome!
