yeah, i'm running Epistane right now; and I've learned very quickly that while on this supplement - I need to be very careful as to what i put in my body. i've had to eat/drink very clean - low salt, sodium, & especially low caffiene! everybodies body reacts differently; i think w/ any cycle there will be times when your mind-f'in yourself and when you are really experiencing discomfort - it's up to you as to when to make the call & better safe then sorry. And like any normal day of your life; your not gonna feel perfect and the same goes for the cycle. but if you had nasty BP levels for 3 straight days & couldn't function then you made the right choice. i wouldn't imagine a PCT would be necessary but keep researching.
