gastroparesis
"My doctor put me on 10 mg Reglan last week for suspected gastroparesis.  I agree with others that the side effects definitely outweigh the potential benefits of this medicine.  Within an hour of taking it, I become extremely drowsy/weak and wanting to go to sleep.  I know that I would never be able to take this medicine before driving.  Then last night, three hours after taking it, I began to hallucinate and was afraid to fall asleep.  When I did fall asleep, I recall having weird dreams.  So, I decided to stop taking Reglan."
