K.....my pwp has just recently increased her dosage of Sinemet, and she has noticed that she seems to feel more tired since having done so. At first, she didn't make the "sleepiness" connection to the Sinemet...actually thought it was the addition of the Amantadine...but, now, she tends to think it's the result of the increased Sinemet dosage...so, yes...I think it is quite possible in this particular instance with you that it just might have been too much Sinemet...your body not accustomed to that extra amount.
