For the most part, I think it is stress. For instance, forgetfulness is not listed as a side effect of Buproprion. Before anyone says that they are having an unlisted side effect, during clinical trials, all someone needs to do is fart, it is then listed as a possible side effect. Actually I think there is allot of truth to my previous statement. So as far as forgetfulness goes, I would look elsewhere. BTW a very good source of this information is
Drugs.com | Prescription Drug Information, Interactions & Side Effects
You need an AD, correct? So IMO you need to stay on it unless something substantive comes along that points to your AD. Also I would not reduce it until you pdoc validates what you want to do. Besides, he would be the best person to understand the possible side effects. For that matter, I have seen people on PC that have problems with forgetfulness despite the med changes they have went through.
There was one time where my body started shaking terribly. I thought that it must be the last medication changed. It turned out to be a medication that I have been on for some time. I am giad I did not start to manipulate my meds. I would have taken away meds that I really needed.
I am not saying that you are doing anything wrong. Please take care. Whatever ypu do, try not to start panicing. I am not saying you are panicing.
FWIW YMMV
