paxil to prozac

my doctor has switched me from 30mg of paxil once daily to 10mg of prozac for the first week, 20mg the second week and 30mg the third week, etc.(for OCD reasons)
my question is how many days do I have to be off paxil in order to start prozac, the pharmacist recommended at least a week, but I don't think this is possible(mentally) as I have been on paxil for 10 years.  I am afraid to start the prozac too soon because of a conflict with the paxil still in my system, but am also afraid of withdrawl (withdrawal) of paxil. What is your suggestion.

You should check with your doctor, but usually you can lower the paxil while increasing the prozac, so you are both simultaneously for a while...but watch yourself closely to make sure that that is not too much.
