I stopped taking duloxetine cause it was making me gain weight, also stopped taking naproxin or aspirin cause im not supposed to cause of kidney issues,im taking nervexol that a doctor here recommended it. is that why my headaches are going bye bye?

Since the FDA doesn't certify supplements like nervexol,which claims to treat nerve issues,most physicians won't endorse them. That being said, if you feel better since taking it I suggest you continue it. Your i may have more information about nervexol including claims of efficacy, precautions and potential side effects &any concerns in people with kidney issues.
