This is how I do it as well. But my side job is not as consistent of income so it affects the gambling budget. Some trips have a bigger BR than others.

 

Seperate savings account that is ALWAYS a trip ahead, that way if I go over budget I'm still not dipping into my "normal" money, while if I win or go under budget, I'm already ahead for two trips in advance. Sadly I've gone over budget the last three trips!

 

I have a separate credit union saving account that has a set amount direct deposited from every pay. It has it's own debit card with a low daily withdraw amount so I can't drain it if I go on tilt. It's my fun money / gambling account only.
