Deposit what you will use in that week and when you have exhausted the deposit you leave till next week or time and deposit what you can afford to loss and not excess amount and thinking that you would win back the money.
We could be working to avert too much gambling but could indirectly not make it to be effective, you could be seeing a bit of relief in depositing all at once for the weekly activities in gambling but you might not no what you will be doing to yourself because gambling is very seductive, you could be saying that you will only gamble small of the money so that others could carry you till the weekend but you wouldn't no when your instinct will mislead you into gambling everything at day one and since there could be game on the following days you could have a taste to try again so actually instead of going all at a time only deposit what you kept for the day.
