The Cerbere33 is very helpfull. I used to have cold sweates with disturbed sleeps and odd fevers nights , nightmares and very tired each morning, as if I was awoke all night long, even if I get to bed early. I used to wake up with headaches. Eversince…I have complete and refreshing sleeps even if I go late to bed; I have my vim back, an amazing clear-sightedness, I’m in good mood each morning and a happier wakefullness! Ready to go to my work as a therapist! Thank you ! I strongly recommended the Cerbere33!
