I was on old school Focalin, which was a smoother cousin of Ritalin (softer landing). They later released an XR version of Focalin because technically you could grind up the version I was on and abuse it. It was amazing. I was literally a different person. I booked millions of dollars of business on that shit. Unfortunately, it probably also contributed to my now chronic insomnia, hypertension, and other heart related issues. I got for stents installed at 45 even though I’m athletic, always active, and hadn’t had red meat in almost twenty years.
