I am really sorry that you can't get the medical help you deserve. Bupropion is an antidepressant and usually not a great deal of help for ADHD symptoms (except maybe for the depression caused by those symptoms). Strattera or atomoxetine can be helpful for some people. It is not as strong and unlike most stimulants it must be taken everyday and usually takes 3 weeks or so to show results. It tends to be used by people who cannot handle the side effects of the normal stimulant meds. listamphetamine or Vyvannse is probably one of the gentlest meds as it can be sprinkled on foods. I am wondering how it did not agree with you as there are really many ways the doseage can be changed. It is also the longest lasting med. Dextroamphetamine is a strong med and you should have started out with no more then a 10mg dose.
Physical exercise can be very helpful for ADHD. But a proper doctor who can guide you through the use of stimulant meds is probably going to be the most helpful. Here is a good link to all the meds our there.. http://www.leeheymd.com/charts/adhd_1.html ...I hope some of this helps.
I agree that while adjunctive, Wellbutrin is not typically a primary ADHD med. I used to take it years ago for mood which improved mood can be helpful but in and of itself did not change my ADHD symptoms. I’ve never taken atomexatine so not sure what form it comes in. I know with both vyvanse and adderall long acting, they are in capsule form. With those you can alter the dose just by opening the capsule and removing some. I bought a cheap microgram scale to do just that and it allows me to adjust the meds to my ideal dosage since what works for me is actually in between the standard doses it comes in. Maybe that’s an option for your med. I would read the literature to check. Both vyvanse and adderall say you can open the capsule as long as you don’t crush the beads. Hope that’s helpful.
