@NewYorker, Here is my opinion to this question of yours, do it for 5 days straight, Pick 5 to 10 sets of lotto numbers, but don’t actually buy the tickets. Just look at the winning numbers drawn to see how close you have come. This will determine how well it’s working for in a weeks use of the spell. If your not close then, I would recommend lighting a white candle with it, and chanting, and use the same candle for a period of 5 days, then play your chances.
