You all are crazy; who say that machine helps you to wake up refreshed. It tried to kill me. It made my heart get loud and strong palpitations, mad me feel like I was on stimulant medication, and gave me the worst insomnia I ever had. I read somewhere on the internet that sleep deprivation kills. The sad thing was no doctor seemed to care. One doctor said well that was the result of the sleep study and that was that. My gp said that he thought it was the machine, but, then diagnosed me as normal and that was that. I have moved to another town. But, before that, I "fired" both doctors. I wasn't even in the hospital for this; but, now I suspect a medical hoax to profit from my medicare insurance. In the meantime, I do suffer. But, this time, I suspect it may be from something gone wrong with my Lithium which I have been on for about twenty years; but now I believe my body is rejecting it and is acting as if it is toxic or a severe side effect. I see a new psychiatrist on Thursday. I just need patience until the n!
