I want to change my sleep habits. I go to bed early only to wake up early, eat something, stay up, and go back to sleep and sleep for a whole day only to repeat that cycle. I go to bed at 10-12 midnight, which is early for me. Then I wake up around 2-3 am only to stay up and do something else. Then I go back to bed around 5 am but it takes a while for me to get back to sleep only to wake up around 2 pm or sometime after. I feel like I miss half a day and I take medication to go to sleep. I know it is not uncommon so I wonder if this is a symptom of mania?
