High blood pressure (hypertension) and Master Cleanse

I have been diagnosed with very high blood pressure. The doctor prescribed Lisinopril (she didn't even suggest I change my diet, but DID suggest I quit drinking beer). I told her I did NOT want to take any drugs. She said I don't want high blood pressure either... true... I haven't started taking the drug yet, and I don't want to. I go back in a week to get rechecked. I'd like to hear from anyone who has brought their blood pressure down with the Master Cleanse. I know it's mentioned in the book, but that was cured with a 21 day distilled water fast. I'd like to know if I'm likely to get noticable results by August 4th if I start The Master Cleanse tomorrow (or tonight!).
I've only been on this cleanse for 7 days (a few months ago), and I didn't even think to check my blood pressure before and after. I felt great on it though!!

Any input will be greatly appreciated!
