I am taking twice as much as you and don't have many bothersome side effects. Just the ones marked with a 'Y" below.

Common side effects of Sinemet include:
dizziness,
y drowsiness,
blurred vision,
nausea,
vomiting,
dry mouth,
loss of appetite,
heartburn,
diarrhea,
constipation,
sneezing,
stuffy nose,
cough,
other cold symptoms,
muscle pain,
y numbness or tingly feeling,
y rouble sleeping (insomnia or strange dreams),
skin rash,
itching,
and headache.
Tell your doctor if you experience unlikely but serious side effects including:
greatly increased eye blinking/twitching,
fainting,
mental/mood changes (e.g., confusion, depression, hallucinations, thoughts of suicide),
unusual strong urges (such as increased gambling, increased sexual urges),
or worsening of involuntary movements/spasms.
Starting dosage is one tablet of Sinemet 25-100 (carbidopa-levodopa) three times a day.

I take. 7-8 senement / day plus the same amount of Rytary. My side effects are weakness and disconesias- involuntary movements: I'm having s second DBS put in my
Brain soon which should reduce the need
For most drugs
Good luck

Simply go to mayoclinic.org, enter the name of the medication in the search box, then read all about the drug. Your best bet is to call your pharmacist (chemist) to obtain advice on the possible side effects.
