Find a dealer and buy some molly off them. Take 1/8th of the molly before the date. Fact: You will get laid. Works for me every time and I don't even try to take anyone back, but the molly does it for you. You basically become the coolest, happiest, most seductive form of yourself if you have it in you.
The 2nd date you can just be sober because the girl will be all "I swear I never sleep with anyone on a first date...this never happens....I really like you." Currently my situation..
Heard it here first.
