Okay so I was looking through the subjects and saw sleep disorders and decided to post this for anyone taking the pill called Concerta and they have sleep problems. Every time I take Concerta after around 12:30 PM, I have trouble sleeping. The solution for this is just take it right when you wake up and if you wake up late in the day being 12 PM then you should consider waking up earlier, taking your Concerta and if you want, go back to sleep. -I WAS PRESCRIBED BY MY DOCTOR TO TAKE MY CONCERTA IN THE MORNING, THIS MAY VARY FROM PERSON TO PERSON.-
