Ritalin (Methylphenidate) taking with a light fatty meal enhances and speeds absorption. In addition, co-consumption of Methylphenidate with Ethanol increases levels of the active isomer d-threo-MPH (Focalin) by 40% significantly enhancing euphoric / mood-boosting effects in all human study participants
Note: it also produces the inactive metabolite levo-threo-Ethylphenidate (which is NOT the desirable isomer d-Ethylphenidate which is VERY euphoric & pleasurable…..in addition to Ritalinic Acid
Pregabalin (Lyrica) is another significant example…….taken on a fasted state C-Max is achieved in 1.5 hours ……after a full meal, C-Max is achieved in 4 hours ………a significant amount of time. I take my oral Brompton Cocktail

on an empty stomach including Lyrica (Pregabalin) it’s full onset kicks in 30min easy …45min to 1h I’m completely lit
