Yeah, other talking therapies and drug therapy (which did make an improvement). I don't think it should make your motivation issue any worse, but yes it does require some energy. However as I've mentioned, it's very individualistic and if you're seeing a therapist, let them know that this is a problem for you and they'll be able to work something out for you. With CBT, you can do as much or as little as you feel you need to really, and a little, if done correctly, goes a long way.
