Guaifenesin / hydrocodone
"This prescription medicine does help the cough. However, expect the side effects as such described to hit home. I experienced all

of the less hazardous side effects. Best thing to do on this medicine is to be able to sleep it off. Says you can take with or with out food but like many medicines try to eat something lite. Not greasy as it can upset the stomach and then posible vomiting may take place. This is my own personal experience with this prescription and it can be different per person."
