I don't think that there is a definitive answer to this.
Probably any of these schedules would work similarly.
Most people would likely say that cycling is not necessary.
However, I would encourage you to experiment and find what works for you.
To start, you could try a couple of variations on a 5/2 schedule.
Variation 1: 5 days of E, then 2 days of P.
Variation 2: 5 days of E&P, then two days off.
Try each of these for a couple of weeks.
At the end of the month, evaluate if one seemed better than the other.
Of course, you should take your AA, every day.
