Addicted

Few days ago, I think since last Wednesay after class, I felt so sick! Sounds ridicilous but it was true, after few days before that I just healed from another fever. My head spinning and heavy while my throat felt like someone is stabbing until I coughed really hard. I layed down and felt asleep after taking 2 tablet of very drowsy medicine. Next day I wake up at 12 noon, I felt so uncomfortable with my throat and again, my head is heavy..After bought chesty coughs syrup with co-codamol tablets, I felt better with very sleepy head. It works for few hours then those pain came back, again I swallowed the syrup and tablets and everything seems to black out. It has been two days now and I am strongly depend on those two prescriptions. Am I addicted to the meds or I am really not feeling very well lately?
