So, you're getting seven (7) hours of sleep.

It's just that instead of going to bed around 11PM and getting up at 6AM for example, your pattern shifted to earlier to bed ... falling asleep 7PM and getting a 'normal' 7 or so hours of sleep. I cannot see how there's anything bad or abnormal about that. Excluding the super old, most folks are probably sleeping less than seven hours. Most folks who are in their late teens, and 20s to 40's should be getting 8 hours but probably do not get that or even able.
