I think you are doing the right thing. A lot of he players hate remembering the cards, but it is essential in stud. One time saver can be to quickly check your own cards. If they are not playable, you don't have to remember the other cards. But you want to be careful not to let this become a tell. You will get faster the more you practice. Roy West has some good advice on remembering cards in his book.
