Herps saturate ever moment of my life as it is both my hobby and my job so I can understand a bit of burn out. Maybe what you need is to try something new. Redisghn all your cages, learn more about the complexities of your animals or maybe just a herp that is new and different is what you need. Also a good herp society is great. Being able to share your hobby with other interested ppl is great fun. Or maybe you just need a break. Just be sure even though your interest is lacking your still taking good care of your herps. Don't neglect them like alot a novelity owners do. I don't think you would but often enough lack of interest translates to lack of care.
