Is this my real personality or just the meds?

After being medicated, I realize that I'm a lot more assertive and confident in myself than I thought I was. I don't question every statement I make, I just say it. I'm able to push through being scared to speak up and then when I speak, I'm not berating myself after about wishing I was more articulate. I want to lose weight so bad; I do not want to be fat anymore but I don't feel like the fat is taking away from my confidence anymore. No, I don't want to be this size but I still have to live while I get healthy.

So if my chemicals were naturally balanced, and I didn’t have ADHD, would this be my personality? Or is this just a side effect of the meds? Can anyone relate? Thanks for your input!
