I'm stuck!  Even though for a month I've changed to doing five sets of 6 and upping the weights... whole body-wise, I can't get above that.  Takes time, right??  If I go to sets of 8 for a month then 10 or so, that's better than creatine ... right?  I understand creatine causes you to retain water, which I do anyways.  A pro-bodybuilder/ trainer at my gym said creatine can help.  I eat a lot of lean red meat but I assume that's not enough.  Resting more might help, though since I train each body part twice a week.  
wow, I can be verbose!
tnx for your feedback!
