Yea I used to enjoy tramadol before I got into OC. So yea I suppose it's not worth it with the seizure risk due to the tolerance now.
The risk of seizures is not only low, but can easily be stopped by benzos.
If fact, there was a paper entitled "Tramadol worst drug for seizures."
The result? 13 out of 87 had seizures.
All were subsequently stopped by benzos.
