Is the standard 120/90/60/30 enough?

I am on the final week of PCT, but have kept it at 120/90/90/ and will decide whether to drop down to 60 or 30. The reason I haven't followed the correct taper is because on the days that I did try 60mg/day this past week (3), I felt a marked increase in high-cortisol related symptoms. After increasing back up to 90mg/day, the symptoms went.

Does the longer-than-usual length of the Test-e cycle warrant a longer/higher dosed PCT? How much longer should I extend it to be safe?

Thanks for any input
