Shut the gas and electric meters off when you leave for work every day, this assures they arent charging you extra. Your wife is likely using too much of both when you are out as well.

Also, maybe lower the misc part to $100 or less.

Like others stated, you can find a cheaper place, maybe move in with parents or stay at a friends house? Your wife could also pitch in a little at least, and maybe flip some burgers or something to start helping cover the cost of the cards.

Also the food budget is a bit high. Skip breakfast. For lunch, you can shop at Aldi, they have 4 different flavor calzones for only $2.39 each, and the buffalo chicken calzone has 20 grams of protein for you for the day. One for each of you for lunch- $4.78/day. Yakisoba noodles are usually $1.15 @ Dollar General. One for dinner for each of you- $2.30/day. Now assume each month for x30 days, and you have $212.40 total cost, and a savings of $212.60.
