Below, you will find quoted material from this website:
http://medicalcenter.osu.edu/patient...ges/index.aspx Both primary and seconary forms of Parkinson's are listed as well as primary, secondary, motor and non motor symptoms. Drowziness is not among them. However, I have also experienced uncontrollable urges to sleep and feelings of drunkenness. I have also experienced lapses in time without a clue as to where i was or what i was doing during the lapse. These episodes almost invariably happened after not spacing my medicine doses far enough apart and introducing too much into my body too soon.

What are the four primary symptoms of Parkinson's?

The following are the most common symptoms of Parkinson's disease. However, each individual may experience symptoms differently. Symptoms may include:

• Muscle rigidity - stiffness when the arm, leg, or neck is moved back and forth.
• Resting tremor - tremor (involuntary movement from contracting muscles) that is most prominent at rest.
• bradykinesia - slowness in initiating movement.
• Postural instability - poor posture and balance that may cause falls; gait or balance problems.

Other symptoms of Parkinson's disease (PD):

Symptoms of Parkinson's disease vary from patient to patient. The symptoms may appear slowly and in no particular order. Early symptoms may be subtle and may progress over many years before reaching a point where they interfere with normal daily activities.
The four cardinal symptoms of PD are listed above. Other symptoms are divided into motor (movement related) and nonmotor symptoms.

• Motor symptoms:
  • Tremor
  • Bradykinesia (slow movement)
  • Rigidity and freezing in place
  • Stooped posture
  • Shuffling gait
  • Decreased arm swing when walking
  • Difficulty rising from a chair
  • Micrographia (small, cramped handwriting)
  • Lack of facial expression
  • Slowed activities of daily living (e.g., eating, dressing, bathing, etc.)
  • Difficulty turning in bed
  • Remaining in a certain position for a long period of time
• Non-motor symptoms
  • Diminished sense of smell
  • Low voice volume (hypophonia)
  • Difficulty speaking (dysarthria)
  • Painful foot cramps
  • Sleep disturbance
  • Depression
  • Emotional changes (fearful and insecure)
  • Skin problems
  • Constipation
  • Drooling
  • Increased sweating
  • Urinary frequency/urgency
  • Male erectile dysfunction

As the disease progresses, walking may become affected, causing the patient to stop in mid-stride or "freeze" in place, and maybe even fall over. Patients also may begin walking with a series of quick, small steps as if hurrying forward to keep balance, a practice known as festination.
The symptoms of Parkinson's disease may resemble other conditions or medical problems. Always consult your physician for a diagnosis][/QUOTE]

i hope this helped.
