I have this

Code:
#showtooltip
/castsequence [target=focustarget] reset=15/target/combat Shadow Word: Pain, Vampiric Touch, Vampiric Embrace, Mind Blast, Mind Flay, Shadow Word: Death, Mind Flay, Mind Flay, Mind Blast, Mind Flay
that I am perfecting. I took 3/3 Pain and Suffering so my SW: Pain get renewed. Well, when the macro starts over it won't do SW: Pain because Mind Flay refreshed it and "A more powerful spell is already active". What is the best approach to fixing this? If I could do a mod in the same macro for only SW: Pain, that would work. Or I could move it to another button but that is one more button to push before entering mindless combat.
