I really wouldn't suggest doing that...once it kicks in it could very well take you to a place where you dont want to go. For example: I once got so high it felt like i was really drunk...staggering all over the place and then passing out on the floor. I dont think you want to be staggering along a trail or passing out in the snow. I would just suggest drinking a fourth of it like you first planned...that will get you pretty lifted anyways.
