Try 3 Drive and 3 RPM pre-workout- and with 2 Drive later in the day.
Drive tends to take a little longer to kick than RPM, and if you were using RPM regularly, and take time off, your cyclic AMP levels will dip temporarily (and significantly)- this is why I recommend stacking the two

This is why the Drive seemed to not really do anything the first couple days- you were getting a good increase of cGMP and cAMP from the RPM, and subsequently good results. When you d/c'ed the RPM and started Drive, the levels of cGMP and cAMP dipped below what they originally were with RPM leaving you feeling a little tired

But when you put Drive and RPM together (highly recommended)- your cAMP and cGMP levels will surge significantly, starting a very anabolic series of events:
Higher cGMP and cAMP levels= heightened anabolism, fat metabolism, and test levels

You will notice a HUGE difference on 3 Drive and 3 RPM, pre-workout, w/ 5-6 Drive a day- we here at AN are learning as we go on this one as well- but you can't go wrong with this stack at those dosages
