Parkinson's Disease
"Pros: Greatly reduces tremors and lasts up to the next scheduled dose, which is the point of taking the medicine. However.....
Cons: Immediately after taking the drug, there is temporary nausea, drowsiness, sleepiness &amp; disorientation, dizziness. It makes me sleep more than desired. I can no longer drive, cook,  or do much of anything because of the dizziness. I prefer tremor relief, so the medicine wins. We don&#039;t have much choice with this disease.
It&#039;s very expensive, but what is your quality of life (what little there is)  worth to you? If I have to exist, I would rather sleep than suffer tremors most of my waking hours."
