Sounds normal for some people and im sure your personal biology effects it. But yeah... That's typically what happens when you don't take stims. Withdrawal symptoms.
I used to get that way by the end of the day when my Adderall wore off. It's sucked. In the end I just stopped taking it because it wasn't worth the rollercoaster ride of emotions. That irritability is what drives addiction. Be careful and tread lightly as you figure out the best usage.
In my case, in America, my doctor just kept increasing my dose... Which ended badly for me. Trust your gut feelings.
