oh, i should add my standard "newb to benzo's" advice: decide how much, *max*, you will allow yourself to take that evening, and hide/make-inaccessible the rest of what you have. benzo's have a tendency to make people re-dose to stupid levels, both because the 'high' isn't what they expected, adn because they keep forgetting they redosed 10min ago (during the half hr leading to the blackout ;P )
/also want to add, since OP is just starting to mess w/ such a strong, addictive chemical - benzo's are some of the most addictive / dependence-causing drugs out there, and tolerance builds quick. and i think the following applies to many people who do/have used benzo's- they're the devil when it comes to the "i did WHAT last night?"-effect
