dsmmcm,

regarding seizures as a side effect of tramadol - check out the PDR or any other current drug guide for laymen or docs. Described as "rare" but I know 2 people who have had seizures caused by tram. Any prior history of seizures of course means you're at greater risk.

As for people getting high on 50mg - personally I couldn't get high on any amount. Means nothing. Every person's response and sensitivity to a given med is different, sometimes dramatically so.
