No rapture or joy

I've meditated for over ten years daily more than 2 hours a day plus I've done over a dozen long retreats. On the first couple of retreats I had quite cathartic experiences and felt a lot of joy. Since then I've felt not much at all. I don't feel any joy or rapture in my daily practice. Sometimes I feel calm but that's about it. I wonder if I'm doing something incorrectly? I pay homage to the Buddha and try to feel gratitude and I practice metta to start. I've also given up eating meat and practice self compassion.
