Gas Prices Up Again…And Again

Every time I turn around, the gas prices have gone up. Every time I need to fill my tank, that is when the price of a gallon of gas increased again. What happens if the gas prices never come down again? How will I be able to pay for normal gas consumption? Even if I reduce the amount of gas that I use, how will I be able to afford the ever-increasing cost? Then I saw an ad about something that looked interesting and said it would let me use water 4 gas. Did I read the information correctly? Does anyone know how this works?
