"blackouts": there are a number of possible causes, but probably most common in a healthy 25 y/o would be sleep deprivation causing brief nodding off episodes. Are you getting enough sleep? If you feel you are getting the typical requirement of 8 hours of sleep nightly and don't feel sleepy otherwise, you should see a doctor for further workup.
