adhd
"I've been on Concerta for about 2 months now. While the effect is much more gradual compared to the "hitting a brick wall at 100mph" effect Aderall gave me, there were some negative aspects. The first week I was a little shaky, which I also had with the other medicines I've tried (Vyvanse, Aderall, Ritalin). First dose always seems to make me feel really depressed and sick, then the next day I feel much better after my dose. Unfortunately, after the first month of use I've built up a strong tolerance to it and it doesn't work for me anymore. Thinking about trying a higher dosage."
