Dear sleepyheads, Reading the range of responses to this thread I suspect that the causes of the episodes of drowsiness reported are in fact very different. Possible causes are: 1. Those experiencing drowsiness since commencing mirapex may be experiencing the drowsiness associated with moving from 'off' to 'on'. In this case the desire to sleep is triggered by the body relaxing in response to the medication. This reaction has been discussed on this list at some length. Perhaps those with a good response to mirapex are truelly relaxing for the 1st time in years. Chewing gum has been mentioned as a means of staying awake. 2. Those experiencing drowsines at a specific time, especially if it is in in the late afternoon should consider asking their doctor for a thyroid test. For many years my wife would nod of on the sofa at 4pm every afternoon. It was even dubbed her '4 o'clock special'. Since commencing thyroxin some years ago the problem has vanished. 3. Those experiencing drowsiness immediately after lunch may need to take their PD meds 30 mins or so before eating.
