Welcome to JustAnswer, my name is Dan and I'm here to help get your problem solved. If you are going through coolant without any noticeable leaks this means you either have internal engine leak such as intake gasket or head gasket otherwise you have a very small external leak such as a pinhole in the radiator or coolant hose. At this point you will need to have system pressure tested with dye in coolant then use a UV light to see where leak is coming from. If your trying to get away cheap as possible a radiator stop leak additive might help since it is a small leak. Let me know if you have questions or if there is anything else I can do to help. Thanks.
