are my snippy, irratable reactions from medication or my ADHD

We are working on our relationship and my ADHD treatment. I realize that this may be more complicated than just one or the other. This has been an issue for us, for a long time. I have been taking Adderall and Vivanse for treatment. I am trying to be aware and speak to my mate in a kind and respectful way but sometimes it just comes out. Would a different medication help be a better fit?
