For summer vacation me and my family went to asia for around 6 weeks and now 3 weeks afterwards I can sleep during night, but my problem is that i'll go to sleep aroung 9 or whatever time I will I end up waking up around 12 hours later feeling pains in my back, neck, and my but nad still fairly tired. When I got back I took out my bed, and now I sleep on a small inch thick memory foam pad. I am unsure if this is because the pad doesn't provide enougj comfort or my body is still adujusting.

Please help
sleep is taking up to much of my life
