Concerta is supposed to last for 12 hours but when I took it, the first 2 maybe 3 hours I felt jittery/shaky and very idk stimulated I guess, but after that I just felt normal and a bit sleepy and exhausted (I don’t have ADHD btw). But yes the effects were completely gone I didn’t feel nothing at all after 3 hours. No issues with sleep or appetite or anything. I’ve heard about concerta crash but I really don’t understand how it just stopped working it felt like I got the whole dose right away but I know that’s not how it works. Does anyone have answers?
