Well that's very general. I mean, do you feel like you could sleep 12 hours and still be tired? DO you get enough sleep? How many hours a night? Are you married/bf? Do they ever say you snore or make noise in your sleep at night?
For me, I could sleep and sleep and sleep and NEVER feel rested. It just seemed to happen overnight- after about a year of constantly being tired my hubby tells me one day "you snore in your sleep sometimes."
I was like hmm no one before has EVER told me this. And I used to share a room with my sister so I'd figure she'd mention it. Then I started looking around online and heard about SLEEP APNEA. Looked it up and was like dang this sounds like me. Went to the doctor and filled out some forms and my hubby had to fill one out too since he slept with me at night. Then based on the questionaire we filled out I did a sleep test and found out YUP I had MILD sleep apnea. I was like mild oh GOD what is it like if it was moderate or severe? I found out I stopped breathing 10x an hour for like 12 seconds at a time!
AND after I got my CPAP machine (which new CPAPs are so much better nowadays) I have never looked back. It took a few weeks to get used to it- but I LOVE IT. I even got a travel case with it in case I need to go somewhere- it's awesome- I won't spend the night anywhere without it.
You might want to check into that if you think that might be your case.
ORRR I'm way off
