Every night this happens to my mother; after the last Carbidopa Levodopa 50mg at 7:30pm and trazodone 50mg at 8:30pm. She gets very calm and sleepy at about 9:00pm but she can't fall asleep. She statys awake until suddenly between 11:30pm and 11:45pm she gets the Involuntary leg movement, sweating and her heart beat goes up as if she working out. She gets confused and is unable to communicate clearly. She finally falls asleep at about 12:30am. Would this be a wear off or Withdrawal symptoms from not taking carbidopa all night until morning?
