It can be frustrating but as your opponants are becoming more aggressive the value of your hands goes up. You start to play tighter your general hand strength when your in a pot increases. combine these together and you wont have to give up every pot - I'd advise against reraising them unless the board is REALLY draw heavy as they will likely not have much of a hand themselves and the only way to make money in this case is too let them get too aggro and try to push you off your hand so calling becomes more profitable than raising.
