i'm taking now ritalin 15 mg (180 pounds) and 20mg, feels wrong somehow, and i really don't wanna split hairs (piils) more then i'm doing now, i'm taking it with strateraa 80, and i've heard that ritalin LA 40 mg = 16 mg regualr.

Ask your psychiatrist.

why? he's not taking it (i hope :) ).i was hoping for some personla expriences, becouse i've heard la 40 mg, is like 16 mg per dose, currently i'm taking 15, and 20 feels a bit off to me.
