I have been on concerta for a past month with 18mg dose. It was pretty eye opening, since i can sustain attention way longer than i ever could, socializing improved, almost all of my issues that i had dissapeared. However the doctor said since my motivation did not improve in the context of increased productivity on the job, he suggested that i should take 18mg x 2. After I took 2 tablets for 2 days it is like i lost all of the good stuff that 18mg 1 tablet gave me, all the boost in prefrontal cortex i guess. I was kind of feeling unmedicated and kinda dumb. I stopped using 2 tablets in the morning and reverted back to 18mg and it took me 3 days to get back good stuff the tablet was giving me. Should i try again with 36 mg and try to take it for the next 5 days to see if anything will improve? Any advice would be helpful
