This is true for me especially when I'm playing casino games and hitting those nice multipliers, there is no way I'm going sleep, what makes me sleep is losing. Even when I place a parley on sports bet, I rarely sleep when it is remaining one game to go. It is even worse when the ticket is holding a decent amount of money, there is no way I'll sleep when the game is live or about to start. This may sound as anxiety but it is not, I see it as simple curiosity.
