Yup so download SSP commands and install. Then as NRGeezyOnThaMic said type '/gamemode survival' into your chat or '/gamemode 0' which essentially is the same command just means you dont have to type survival.
You could download SSP as said up there ^. Or you could download TooManyItems. It has options to switch to creative and back. It also has things like time and rain.
Single Player Command "Gamemode Survival"
