Go back and play episode 1. that's what he was doing. An IV bag like that would last maybe 8-12 hours. Rick probably woke up one to two days after it all turned south. Maximum amount of days a human can go without water = 3, and that is IF they are well hydrated to begin with. And by the end stages of Dehydration he would have been suffering, delusional, and not in any shape to even recognize where he was.
So Rick woke up one to two days after it happened. I would say Episode 1, Herschel's farm, the pharmacy, or the very beginning of the motel stay.
