d0gma,

What you most need nutritionally to make dopamine is high quality protein, which you are probably are avoiding if still on Sinemet. So you are somehow going to have to balance increasing protein while decreasing Sinemet. Breakfast is crucial. Either eat like Thai people [eat your left over dinner of beef/pork/chicken stirfry and egg fried rice for breakfast] or eat like the Dutch do for breakfast [lots of slices of unprocessed cheese and cold cuts of real homecooked joints of meat]. You won't know yourself.
