Kylie,
15-20 Tramadol per day is WAY too much; the
maximum dosage per day is 400 mg, or eight 50 mg pills. You’re taking more than double that. As stated above, the seizure threshold with Tramadol is very small, as it contains an antidepressant. If you continue, I fear you will continue to have seizures...which can be fatal on their own or if, God forbid, you were to have one while driving.
