My gambling strategy is that don't bet too much just bet in small amount and just enjoy of what you are doing. Don't put all your allowance in gambling so that in the end you will gonna blame yourself. 
This is a good gambling strategy that you are not going too bet too much and it is better if you are going to put limits also for your loss not just to the money that you are going to gamble.
Maybe 3 consecutive lose is enough to stop for that day.
