Stop the clock

Hi, Does anyone else have a symptom like me.I take my meds every three hours, but at the 2030 hours  intake EVERY night I take my meds and within 15 minutes I totally stop,  t then dont restart until after the next and last of the day at 2330. I take co-careledopa,

how very strange. you dont have a cup of milky drink before bed? any other night-time meds? alcohol?
