Okay so I went ahead and did some quick research, it appears that IED
can occur later in life, based on this excerpt:
A 2006 study suggests that the disorder is considerably more prevalent than previously thought. In a study of almost 10,000 individuals 18 years or older, lifetime episodes were reported at 7.3%, while 12-month occurrences were reported at 3.9%.

Also, something of serious interest to you:
Prevalence is higher in men than in women. The disorder itself is not easily characterized and often exhibits comorbidity with other mood disorders, particularly bipolar disorder.

You should *definitely* consult your psychiatrist about this.
Lastly, I just found this citation in an article I was reading on the subject:
Adrian, N. (2001). "Explosive outbursts associated with methylphenidate."
Journal of the American Academy of Child and Adolescent Psychiatry.
However, as tantalizing as finding that article's citation was, I simply
cannot find a full-text readable version online, nor any more of an abstract than that. But apparently there is, indeed, a published link between methylphenidate and explosive outbursts. Pursue this further, man - interesting, interesting!
