Hi there, I apologise as I did not pick up on your original letter but I gather you are recently diagnose. I assume you are only on Requip at the moment. Does your tiredness seem to peak at a certain time after taking medication? If so it is probably due to your meds. and probably can be adjusted by your Neurologist. One of Psrkinsons little tricks is to saps one strengthsomedays I feel just exhausted all day. This is a symptom of PD yes and I do get the overwhelming feeling that if I do not lay down I should fall down with exhaustion and it seems a mere 5 to 10 minutes of lying down will cxompletely take it away and I am ready to carry on with whatever I was doing. Nap attacks are completely different you do not know it is happening until the split second that it takes and you come back into the big wide world.It must only occur over a split second as I have fallen of my chair in front of my old Cow "Gateway"or hit my head against the screen but I come to and feel as if nothing has happened. The sleep study showed I never reach REM stage of sleep and am now on Klonopin 1 at night I certainly am sleeping for more than a couple f hours at a time and feel more with it in am.I have only been taking it for a week so a bit early to tell but I still getting the sleepy feeling about 3 pm and 6pm that points a set time after taking PDMeds whuch are Sinemet Sinemt CR EldeprylMirapex.I feel have increased since Mirapex.Thepoint now is to define which of these is causing my nap attacks?? the 64,000question of the week Hang in there once youbecome aware of all the symptoms of PD if yu have a god Neuro will bw able toset up a good meds regimn. Good Luck Margaret 48/12/60 and thank the Lord with a very strict meds, program an excellent neuro and the love and help from my family I still can be a wife mother and nana to them all.
