I saw my neurologist on 12/22 and told him of my sleep problems along with many on the net. I go to sleep eaisly but then wake up from 2-5 or 3-6am. He suggested that I take 1/2 a sinemet CR 25/100, at bed time,for a week and see how that worked. If no positive result then take 1 25/100 sinemet Cr. Try for a week, at bed time, and if that dopesn't woprk take 1/2 a sinemet cr 50/200 for a week, at bed time. If that doesn't work take 1 sinemet cr 50/200 at bedtime and if that doesn't work quit. I normally take 1 sinemet cr 50/200 in the morning, 1/2 a sinemet cr 25/100 at noon and 1/2 a sinemet 50/200 at 4 pm. I have now taken the additional 1/2 25/100 sinemt cr at bed time for seven nights and have slept through the entire night. I did not wake up groggy and it seems this may be a solution.
