Is it still insomnia if you make up for the sleep you lost later?
Like, what if you got in the habit of making up for a sleepless night by catching the missed zzz's during the day? Is it still insomnia if you manage to sleep the reccomended amount but at daytime?
Not so much insomnia, but definitely a sleep disorder. Some people, like myself, are cursed by a genetic mutation called the after-hours gene. It is speculated that this gene is responsible for regulating the body's internal clock (the circadian rhythm) and those who possess it work on a 27 hour day instead of 24 hours like normal folks. If you don't have any reason to be up in the morning just stay up late and be proud to be a night owl. If it is something that bothers you, try taking a melatonin supplement. Melatonin is the hormone that makes you sleepy; normal people start secreting it around midnight.
