I'm starting a MC tom. morning but have a ? re. coffee! Please RO>>>

I have been drinking 3 cups a morning for the past 15 yrs(and I'm only 31!). I am very serious about this Master-Cleanse but am quite scared about the caffeine headaches that will certainly happen---that they might even trigger a migraine. Should I .....

1)Do the Master-Cleanse the right way and deal with the consequences not matter how hellish they may be
2)Do the Master-Cleanse but for the first 3 days have coffee (but in lessening amounts---1 cup,1/2 cup,1/4 cup)
3)Do MC the right way BUT take Excedrin for the first couple of days
I should note that I have a family(4 kids!) so I need to be there for them. I AM serious about doing this however and plan to go AT LEAST 10 days, more than likely 2 weeks. This is for detox/cleansing AND for weight loss(I'm 30 lb. overweight and got there in a very bad way).

Any help would be GREATLY appreciated! :)
