have experience with Mirapex induced sleep apneas and hallucinations. Both were fairly mild in my experience. They both went away inside a year of starting Mirapex. Sometimes I would have to pull off the road and power nap for 15 mins or so, so I would not fall asleep driving.
The hallucinations were brown streaks in my peripheral vision. Once I realized what they were, I got used to my "little furry friends"!!
