My ADHD medication schedule is fairly ridiculous. I take 30 mg Ritalin at 07:35, followed by 10 mg at 09:14, 10:37, 12:00, 13:21, 14:41, 16:00, 17:17 and 18:33.
What's so special about those numbers?
They are at 99, 83, 83, 81, 80, 79, 77, 76 and 72 minute intervals to create the linear serum level increase in the image below.
My serum levels are going to be much lower than 22 ng/mL. I weigh about 130 kg, so this much per day is a reasonable number of mg per kg for me.
