does anyone else get in a bad mood when they are on antibiotics? im usually a pretty relaxed person but it seems like when im on a cleanout with iv antibiotics i turn into a jerk. i've been flipping out on my parents for no apparent reason and looking back and wondering why ive been so meannn? do you think the meds have anything to do with it or could it just be the annoyance of the i.v. and feeling run down?
