Homatropine / hydrocodone
cough
"I took the recommended dosage before bed when prescribed for bronchitis to help suppress cough and allow me some rest.  To my extreme disappointment and surprise,  1 hour later I feel blanketed in a thick,  heavy fog but completely unable to sleep because I'm WIDE awake.  For hours.  I can barely lift my head off the pillow and if I do,  I'm in a world of awful swirls,  dizzy,  and I'm trying to get my confused body to the toilet before I'm throwing up in my bed.  24 hours and 15 vomit sessions later, I'd rather have bronchitis.  Never.  Again."
