i've noticed for awhile now, that anything and everything can trigger irritation. i've been put on several pills before including depression. i recently found out i'm anemic. and i did some researching, and it said anemia can cause irritation. however, they gave me zinc pills. i'm required to take one a day, in which i do. i however, still am irritated. my sister gave me vitamin a pills to try. i'll probally start trying tomorrow, are there any more suggestions? because i'm tired of taking out my frustration on everyone else and not even having a soloution.
