Hi Dr. Rynne, I have taken SSRI's and SNRI's before and have had problems with anxiety, feeling aggressive, etc. My doctor put in my chart, allergic rx to Effexor. He has since started me on Concerta. I know its and NSRI, but will it have the same effect on me as the others? I'm just worried - due to the reuptake of norepinephrine. Isn't my reaction going to be he same as it was on say, Effexor? Hate the feeling, would love to avoid! Thank you for your time. Cressa Sullivan
