That's very true, it happened to me once and I hated myself all month. I made a partly of 7 European league games and was looking for a total odd of 10.0 but I was still far off so I decided to add a game from the Brazilian league which was going to be played at dawn 0:15GMT. I had all my 7 games won but that game and because I was looking to settle a debt with my win I was keen and stood awake all night until I got tgat disappointing results which made my head go nuts. So people don't loose your sleep over bets , they can make you sick if you loose.
