Want to eventually do Master Cleanse but I am very unhealthy, where to begin?

I am a 39 year old female who is desperate for good health. I have read about Master-Cleanse for years but never had the guts to attempt something so drastic.

Background: I had my gall bladder removed 15 yrs ago. I developed IBS after that surgery. I also have a condition called spondylolisthesis with a natural fusion of L4, L5 and S1. 7 yrs ago I was (mis)diagnosed bipolar after a horrible episode of postpartum deepression. I stayed on those meds for 6 yrs until I found an excellent therapist who showed me I was misdiagnosed. My teeth have chipped, I have major yeast issues, high blood pressure, high cholesterol, rashes, thinning hair, dingy whites of my eyes, Arthritis and now an extra 60 lbs. 16 years ago I ate very healthy and exercised daily and weighed a healthy 120 lbs, now I weigh over 200 and feel like crud everyday.

The only meds I am on are for pain and Arthritis of my spine and antacid for my upset stomach due to the Arthritis meds..lol. I was prescribed bp meds yesterday. I DON'T want to take them.

I was going to start the Master-Cleanse but found this site that recommended doing other flushes before beginning the MC..so what to do first? What book to read prior to the mc? BTW, I tried to talk to my dr about alternatives to medications and she blew me off, so no support there.

Thanks for any support you can give. I want to do this thing right. I plan on eating healthier after I finish all the cleanses (flushes). I am not doing these for weight loss, only as a precursor to a lifestyle change which will hopefully lead to weight loss!
