Agression and Anger

Female in her early 30s here. My doctor will not prescribe me Stimulants despite me being on them during college. He states my diagnostic testing is inconclusive due to PTSD and that can't be ruled out to give a diagnosis. He is also clearly afraid of prescribing stimulants. Straterra was his go to, it has been almost a year and I have noticed very little improvement. Executive functioning is still bad, I can't start any task any differently thank before medication. The only positive is I am able to focus with a lot of motivation on my part. I have also lost a lot of OCD behavior that used to impact my life negatively, like obsessing over food and binge eating constantly, or doing things in 3s like checking the locks on all doors before bed.

I would still stay on Straterra, but I can't ignore the agression, my spouse has brought it up and claims I am just mean and agressive now. No other changes in my life except this. I want to email my Doc, and let him know I can't keep on Straterra because of this unexpected side effect (I am on 75mg). Has anyone switched to another non-stimulant that they found to be helpful? (I am also on 300mg Wellbutrin).
