Brain Tumor / Parkinson's Decease

Hello to all you helpful kind people, thanks for your advice its greatly appreciated, its just a matter of playing the waiting game, horrible horrible waiting, but like everyone else you have just got to get on with it. My husband has been on the sinemet for 3 days now just 2 a day (first day just 1) I know its to early to tell but his tremor seems a little better, he actually did not fall asleep whilst sitting watching TV last night, which was an absolute first in yonks, but he has been falling asleep all day today!!!!! could anyone tell me if the sinemet can cause really awful sour smelling breath? as its most noticeable today how bad his breath is, or is this one of the other symptoms with PD? just thought some one might know? thanks a million to all love Hols x
