Myself, once a week.
I mostly bet on sports, sometime there's a week where an underdog win more than favorite, sometime there's a week with full of unpredictable results. It's random and depend on how lucky your predictions is.
You're right sometimes I don't even feel anything like I needed to gamble and that's because I take gambling as less important and avail myself when I think it's best to do so, which is during my free hours aside of work and other schedule but recently I came to understand that doing this will eventually keep you atvlow cost of loosing and addiction if any gambler be consistent in this act.
