hi, i am currently prescribed 40mg of vyvanse and 5 mg of focalin. i do not believe these are working, i know i may need to up the dose, but when i went from 30mg vyv to 40mg it only worked for about a week, and only lasted about 5 hours which is why i take focalin. after taking these for a few months it pretty much stopped working completely. is there anything i can do differently besides constantly upping the dose? because if i do that ill be at the max within a month. please advise, this stuff really helped me when it worked.
