Car overheating puddle of liquid from under the car?

Acura Integra 96. I was driving my car pretty much all day today when i parked the front up up on a curb for a min and left it running then i got back in it and started driving when i realized it was overheating like all the way over to the H symbol. So I pulled over and topped off the coolant which took like half the jug which made me think theres a leak somewhere. So I started driving it again and it stayed normal temp for about a mile then it started overheating again so I pulled over and looked under my car sure enough there was a puddle of liquid under it. So I checked the coolant levels again and noticed it was empty again so i put more in started up the car and checked where it was leaking from except it wasnt leaking while in park and it wasn't overheating anymore. So basically it leaks when i drive it and its coming from the left side of the car if your facing it from what i guess is the overflow tank but, im not sure theres a hose that connects it to the radiator so im uming thats what it is. The overflow tank makes a sound like its bubbling or draining i cant tell when its overheating but it stops when i take the cap off the radiator. Any thoughts on how I should fix.
