Now this is going to sound weird. 
Get this feeling of depression General malaise when I lie down, like if I want to take a nap or just rest my eyes ( but not when going to bed at night). Do you have this sort of feeling when I wake up in the morning from a restful sleep. 
  And when I do rise from lying down otherwise, feeling does dissipate for the most part
   50 something yr old, dealt with depression/anxiety most my life, on medication for this since my 20's.
   Anyone else experienced this " lying down issue"?
