What not to do before a PSA test

My 6 month PSA test is coming up soon. What do I need to not do before the test?

I know having sex is one of the things but how long before the test do I need to abstain?

"Ejaculation, bike riding, or any manipulation of the prostate, such
 as a DRE [digital rectal exam], all have the tendency to raise the
 PSA in the blood. "

I've just had a quick search through assorted sources for tips about what to avoid.
48 hours seems to be the consensus when it comes to sex/ejaculation.
A couple of days would also seem about the norm for minor things like cycling, horse riding too.
A DRE is a bit more of an interference so a couple more days.
The big thing to avoid is the doc giving you the DRE first and then drawing the blood.
It takes about 6 weeks for PSA to settle down after a biopsy
And BHP and other infections are a bigger influence still, and may take months to stop affecting the results.

Do the same "rules' apply to folks who had their prostate removed and those who didn't regarding sex? Uderstanding that the
physical process is different after rrp.

Are there things to not eat before a PSA test? I know eating a lot of salty foods
before a blood pressure test will give higher than normal readings.

What about going to the fitness center?

I want a real result that I don't want to be artificially inflated.

MY opinion, fulltlt: If you want a regular test, then the regular process is to abstain from sex for 3 days beforehand, no bike riding, including recumbants, no DRE beforehand. If you do this every time, regardless of whether you have a prostate, then you have created a set of conditions that is repeatable and will give you the same condition each time you are tested. Altering things only gives you altered results.
