Sasha, sorry for my fuzzy suggestions re taking divided sinemet doses after dissolving in water.
Because I automatically think about volumes quantitatively, I assumed that others did also. When i suggested "a measured volume of water" I was thinking eg, 100 mg tablet in one cup, then sipping measured fractions of that; 1/4 cup at a time to take 25 mg, etc.

Paula, you know that everyone on the forum is pulling for you with all our might! I'm confident you will pull through this severe trial. Praying for quick resolution.
Robert
