Trouble Sleeping

I’ve been having a lot of trouble sleeping.  I keep waking up at 6am no matter what.  Then I can’t go back to sleep until 9am and end up sleeping until 12pm.  I usually go to sleep between 1am and 2am but no matter what I keep waking up at 6am and can’t go back to sleep.  I also have trouble getting comfortable and sleeping on my side.  I sleep on the couch every night now.  It’s the only way I feel comfortable enough to go to sleep.  I guess the side of the couch hugs me kind of like a pregnancy pillow.  I don’t get leg cramps from sleeping on the couch and my head is elevated a bit which keeps me from getting acid reflux.  I do miss sleeping in bed with my husband but the couch is the most comfortable place for me to sleep and seemingly the only place I can actually fall asleep even if I still keep waking up at 6am.
