Welcome Karina!

The flat feelings may be caused by the fact that your system has become used to or become accustomed to your present dose of medications.
I take the Abilify at a 10mg dose but I believe the max dose for it is around 30mg per day.
I also have ADD/ADHD and take Ritalin for that too.
You may just need to share these thoughts with your current doctor to see if an increase in one, or all of your medications would benefit you.
Hopes for a good day!
