Definitely. The limit is easily set by simply refusing to comply with his demands when you feel they are unreasonable. For instance, if he asks you for water, you can go and get it for him (after asking him to say "please" of course!). When you come back with the "wrong" cup and he starts screaming about it, you can say, "I'm sorry. This is the cup we're using for now. You don't have to have the water if you don't want it." This will lead to lots more screaming for the moment however once your child has experienced this approach several times, he'll begin to realize that you aren't so impressed with his screaming. He'll then stop exhausting himself with it because it's not getting him anywhere anyways. So try that approach for now and good luck!
