Well, I'm not tempted to buy lottery tickets just because of the jackpot. Often, I just buy (regardless of the jackpot prize) because I have a numbers in mind. Before, i'm a regular bettor of keno lotto (if you're familiar with it) and also had the chance to win a decent amount solely because of luck. But in national lottery I don't often bet, i'm not certain if there's a winner already of 6/55 lotto but what I saw on the news are, someone got lucky in 6/49 super lotto, winning over $11 million dollars, that's quite huge.

For me there's nothing wrong if you want to double your tickets to increase your chances. However keep in mind that lottery is a game of luck so have less expectation to not regret using your money just to buy tickets.
