"i am taking 54mg for inattentive add its only been a month of taking concerta without breaks, but i feel i have the general feeling down. i can focus with minimal distraction. after 3 weeks i am feeling the loss of appetite, lost 6lbs in one week and there is only a period of about 5 hours i can feel it work, during that time i love the motivation i get and am more social. all in all it does what it&#039;s supposed to but for only around 5-6 hours, after the working period i am easily aggravated and my add is worse than ever. my anxiety was high at first but after a month i feel like it is less of a problem for me.
