There are different recipes for post cycle, some prefer clomid and some hate it cos of side effects like clomid blues and clomid moods. Post cycle depends on what works for you, I mean if I use clomid for more than two weeks I get the blues. So I guess you have to test it out cos you may respond differently, clomid is not compulsory.
I'm gonna give this 'unleashed' a go from PF for my next post cycle to see how I recover. I have yet to find a decent recovery cycle yet.
