Sick AGAIN!

So I´ve been really sick right, and someone told me it would be a good idea to take codeine (Can you believe it comes over the counter in pill form?). I am not really ever sick and I never take pills, so I have no clue, so I take it, and then I hear it´s bad so after about two weeks, I stop. I read to find out what is the big deal with codeine, and I learn that it´s a painkiller (used for after-surgery), extremely strong, and derived from opium, and 10% of it is transformed into morpheine in the body! AH! No wonder I was so happy when I was sick! Then all this week I have been really sick, and feeling like blecch (I probably had withdrawal symptoms), and I started taking another medicine. I was so sick on Thursday, and cold I was shaking in class and wearing other people´s coats and scarves. I was NOT about to leave the class because you are only allowed three absences in the semester and I want to save my absences for traveling right? No wrong, because the professor saw me and made me go home. DARNIT! I am bitter, I could have went to Barcelona or France this weekend, but my body just doesn´t want to cooperate with me. So I wasted another weekend willing my body to hurry up and heal.
