Hi. I was diagnosed with PD in June 2012 I am currently on 100/25 Co-careldopa, x3 per day, 2.62mg Mirapexin & 10mg Seligiline. My issues are that I am constantly tired. I tend to grab 4-5 hours sleep at night but wake at around 0400. I'm struggling to stay awake at work throughout the day at the computer. I'm then frustratingly failing to stay awake throughout the course of the evenings. I have been known to fall asleep at social gatherings rather embarrassingly. I regularly exercise by either cycling, jogging or yoga. Any suggestions please?
