About six months ago I bought a weighted blanket and have been sleeping really good. But as therapy gets to more core trauma I've started having smell flashbacks. About sundown I start smelling cigarettes and ash. By midnight it's intense and I'm in a manageable panic state. I usually fall asleep around 130 or 2 and up at 5 for work. I've used all my meager vacation time to get some sleep so I can function. Any suggestions?
