Also check that the room you are sleeping in is well ventilated. A common reason for lack of energy feeling the need to sleep more is not enough oxygen during your sleep. If you sleep in a small room do so with a door or window open to provide enough ventilation.
Failing that go outside and breathe!!!! In fact pick any paraliminal tape sit outside in fresh air and listen to tape with spine straight so you can breathe properly. Check out how you feel after that.
Hey if you really feel the need to sleep then do that. Make it ok.. if you really feel that you are sleeping too much, you first need accept that you want/need to do that, only then can you intuit what you need to do change. It quite possible that you're sleeping to much (in your opinion) due too the fact that there is something you are trying to avoid...perhap falling back into your former addiction? But like I said make it ok.. if the problem isn't caused by a health problem or environment then you'll find the answer/solution once you're cool with it.
