"36 year old female diagnosed with adhd. started on concerta 30mg daily (2 weeks), no therapeutic effect but had extreme dry mouth, a crash/grogginess in the evenings. switched to adderall xr 20mg daily, no therapeutic effect; experienced dry mouth and slight loss of appetite during day, made up for it in evening. just started 40mg daily and i feel the therapeutic effect. profound concentration at work, desire to tweak processes, love getting things done, a non-stop interest in being productive with everything. i have this sense of crystal clear clarity of my surroundings, like hdtv sight. around 5pm, i still feel a crash and extreme tiredness. i will see if i can take a short acting pill to get me through the evening. very pleased now."
