I have a friend who has a tendency to see her regular doctor plus go to free clinics and sometimes forgets to mention all the medications she is on while at the doctor.She is now taking neurontin,klonopin,hydrocodone with ibuprofen and flexeril. After taking her meds she basically passes out or goes to sleep . Is this to many synergistically additive central nervous system depressants for a person to take at one time?
