If you say Ritalin, you mean the "normal" version without extended release, right? It is individual how many hours Concerta has an effect, but it's roughly 7-10h.
How much mg of Ritalin do you take in 7-10h in total? That is roughly the dosage you need for Concerta.
Discord recently added "user installable apps". You can configure it though the installation context. I have only implemented the usual server installable apps so far, so I don't know what the apps in the new context are able to do. But it might be worth a look :)
