I am soooooooooooooooooooo hyper today I have no ritalin left I cant get my script for three weeks just got new drug insurance company and they told me I need prior authorization on ritalin because of my age they said the max age they prescribe it to is 18 and Im 22 Ive been on ritalin since elementary.  Now Im sooooooooooo hyper I cant sit still Im all over the place.  I cant pay attention either I daze off...   I daydream when Im sopposed to be focussing on stuff.  I need to calm down I need to focus but Im soooooooooo hyper.  Im not even acting my age I had one of my fits today when I got frustrated which usually happens to some people who have ADHD when they get frustrated it usually falls in to a tantrum.  when Im on my medication the tantrums are not noticable Im able to pay attention Im able to concentrate and Im able to stay calm.
