As a veteran and currently going through the VA for ruptured disks in my back that seems to be all they wanna give. I have to chew about 10 at a time to get any kind of effect. I've taken as many as 20 at once which I don't recommend doing. All I can say is that tramadol has SSRI qualities and taking too many can cause seizures especially if you are already prone to them. Be careful is all I'm saying.
