Hello
Thanks for posting your query at DoctorSpring.com
ADD is a difficult and distressing condition and should be aptly treated. Its unfortunate that ritalin did not suite you. However there are plenty of other options like adderall or atomoxetine or bupropion which can help in ADD. Of these adderall is the most effective and should be sincerely given a try. Normally these medicines start acting fast and the response would be evident within 5-10 days.
Hope this helps
In case if you have any further queries, do let me know.
Kind regards
Dr. Srikanth Reddy MD
