I take concerta in the morning and ritalin at the end of the day. What ever dosage, It has the same affect on me (The original poster) until it wears off. That's what it's supposed to do I guess which is to calm the mind down and stop distractions, help focus etc. But maybe if I took amphetamine, I wouldn't have the sadness unmotivated effect. But I'm not going to mention it to my psychiatrist because he says that they're all the same meds just under a different brand which is ridiculous but there's nothing I can do at this point. The methylphenidate works great other than this side effect so it's not worth asking for something that has such a terrible reputation.

Also, who ever said that an antidepressant could help with the flat effect related to stimulants, I don't think that would work tbh but you can try.
