exactly the same. Just one nights poor sleep and the overcompensation of the mind makes life a living hell. Anxiety, depression and feeling like in a haze is absolute torture.
Poor sleep I would think is different than no sleep. The nights I get poor sleep, approximately 2~3 hours or less, the following day would be nothing but intrusive thoughts, depression about those thoughts and exhaustion. The nights I had NO sleep the following day all of those symptoms would virtually be gone.
