Good & bad days with Sinemet

I have Atypical Parkinson’s & I started my full dose of Sinemet about 2 months ago
[2 pills x 3 times a day]. I have been very pleased with how I have been feeling after starting with Sinemet. My stamina in particular seems far better than it was
pre-Sinemet.

My main issue is mobility. That is walking & freezing when standing still.

My main & only activity is indoor bowling. I had a recent run of 12 days where
I played every day without difficulty. But one day this week I had to stop playing after 5 minutes as my feet / legs had frozen & I could not move my feet.

After recovering a bit I went home. The following day was as bad but today I feel I have recovered enough to play bowls again.

I do wonder what caused these episodes.

Anyone else have this problem?

Best wishes
