My physician recently increased my dose of carbidopa -levodopa because I was experiencing extreme off-effects [e.g. cold sweats; cold extremities; a sudden fatigue, decreased communication skills, and balance problems] about 90 minutes after taking the medication. The first day I received the higher dose, I became hyperactive; very jittery; rapid speech; lost balance and cravings for food, all very unpleasant. Anyone else have similar symptoms?
