Does it drop suddenly if you stand up from a sitting position suddenly ? This is a symptom of PD, its called Orthostatic hypotension. Also it could be interaction of some other medicine you are taking.

I am taking this medication 1 and half tablets three times a day and my pharmacist told me to take it immediately after or with food, that helps. I also take blood pressure medication, it helps not to stand up too quickly from a sitting or laying down position.

Just a carb levo. My doctor contacted me and told me that this should level out as medication levels out in my system. I'm now taking two doses in the morning one in the afternoon and one for dinner. Hopefully this builds up and lasts longer more than 3 hours period thank you for answering I love the site

When you say "I'm on this medication..." are to referring to a blood pressure med, or the Carbo-Levo ?
A drop in blood pressure is a common problem with PD meds.

Just reminder - keep meds away from meals ! :) If you find the stiffness outlasting the meds...cal your Doc.
You may need a "bump up" - and don't worry - dyskinesia is manageable. Why live with the pain ?
