Does add meds or the absence of add meds mess up a persons personallity?

Complicated: Add meds may or may not affect a persons personality. It's important to learn about possible side effects and have people who know you well let you know if you are behaving differently. Some people are told they behave better or worse, or experience better or worse mood. Some people are depressed or anxious because they are disorganized, some become more aggressive and have negative effects.
