... the other day I took four 50mg tramadol and 3 hours later I took five more, so I ate 450mg in a short while. a couple hours later i had 2 seizures. never had seizures before. wondering if this was a tramadol overdose? didnt tell doctor that i had been taking tramadol, didnt want to admit that i had taken so much. my regular doctor is on vacation but i did make appointment with him next week. i know that just because my usual dosage is so high doesn't mean that i am not susceptible to overdose but didn't know for sure if these seizures were brought on by tramadol o.d.
