Hi jo h
I too suffer from dyskensia after taking stalevo. I am taking 1 x 150mg at 8am and then 3 x 125mg every 4 hours after until 8pm. The dyskensia can start at any time ( sometimes after only 20 minutes ) but normally about 3/4 hour , and finishes about 1 1/2 hours after taking. Depending on what I have eaten protein wise, it can last up to 3 hours , so little time being normal when that happens.I also take amantadine, but only 1 x 20mg in the morning as they can cause me sleep problems. Everyone is affected differently, and you just have to try and work out what is best for you. You can get help from the PD Org, or I have a community specialist Parkinsons nurse assigned to me who I see every six months , and can call anytime , who is really helpful . When you feel a bit more confident , you will find that you can make some adjustments yourself, and experiment to see what is best for you.I also see my Neurologist every 6 months.
I can't tell you what will work for you or that it will get better, I have been assessed and currently waiting for DBS , which in my case the neurology team hope they they can reduce the dyskensia. I can't wait for this, but the operation keeps being cancelled due to lack of beds.
