You may want to look into a sleep study (assuming you can afford it or are not American). There are some sleep problems that can cause you to not feel rested even with a ton of sleep.
I wish I could, but I can't for the same reason I don't sleep restfully these days. I am currently living in two different states trying to sell my house in one state while packing and painting and fixing everything while simultaneously opening up a new branch for my company halfway across the country and dealing with employees in both states who don't seem to understand I'm only one person, and just a normal human at that, and if that wasn't enough, I'm the type of person who can't say no and I overchieve everything. It's stress but it's the kind of stress I can consider good because the way my brain works If I sit still I might fucking explode. Pretty sure I'm ADD but in a way that I've learned to take advantage of it because I'm not medicated or anything. The plus side is I'm getting ahead in life for once and eventually I will over do it to the point I break down and it all becomes someone else's problem while I chill in the psych ward taking to myself about things that aren't real lol
I exaggerate a bit but I'm fucking wired for sound and no one will stop me because life is short and I've got shit to do. I'm fortunate actually, because I love what I'm doing but it will fucking break me one day if I'm not careful.
This is not medical advice, but assume your sleep is fucked for a reason, if you actually feel like you're sleeping during that time, the most common reason by far is sleep apnea. If you have sleep apnea, the best solution is likely going to be losing weight and exercising or buying an expensive machine to sleep with (probably both to start with).
However, getting to the point... the cheap but not nearly as good solution is to sleep on your side and use breathe right strips. You may not sleep well, but you'll sleep slightly better.
