Hi ,I've tried Dr John Grays (Mars/Venus) amino acid shakes and it's helped w my tremors. I've got PD and need to decide to go his direction(Dr Marty Hines) w the amino acid regimen or take the conventional route w sinamet. I've got other issues than the tremors as we all seem to. You can't do both due to the protein

Thank you so much for this information. I will look into coconut oil.

As your husband also has dementia, I strongly suggest researching deeply ketogenic diets (heavy on the coconut oil). Look up in particular Dr Veech's work, Dr Mary Newport an Dr Brain Fife. As a starting point, listen to the pod casts on "Parkinson's Recovery Radio" website.

Here are the more well reported side-effects (i.e. those listed on manufacturers leaflets):
muscle stiffness,
tremors,
spasms,
and poor muscle control.
dizziness,
drowsiness,
blurred vision,
nausea,
vomiting,
dry mouth,
loss of appetite,
heartburn,
diarrhea,
constipation,
sneezing,
stuffy nose,
cough,
other cold symptoms,
muscle pain,
numbness or tingly feeling,
trouble sleeping (insomnia or strange dreams),
skin rash,
itching,
and headache.
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.
May interact with other Parkinson's medications, metoclopramide, isoniazid, phenytoin, papaverine, blood pressure medication, antidepressants, or medicines to treat psychiatric disorders. Tell your doctor all medications you use. Sinemet should be used only when prescribed during pregnancy. Levodopa may pass into breast milk and affect milk production. Consult your doctor before breast-feeding.
