Twin Labs is a company that has many powder products, available at General Nutrition Center stores. I was there yesterday and asked what they had that was high in carbohydrates and low in protein. ULTRA FUEL is a powder for an orange flavored drink with 0 Protein and lots of carbohydrates. This may be a suitable drink, as far as not interefering with Sinemet. I didn't look at all of the nutritional information closely, but I know these types of products are loaded with good vitamins. If you go looking for this be sure to ask for ULTRA FUEL. Other products with similar names come in similar containers but are not low-protein powders (Opti Fuel, Gainer's Fuel, etc.).
