Hold on a minute kids, this "they lower the seizure threshold" is complete and utter fucking horseshit. That only happens in about 1% of the people who take an absolutely gigantic overdose (700mg+) and who are already vulnerable to seizures. I'm not sure which fuckwit first started spreading this urban myth but lets not spread it anymore. It seems to be the only thing people "know" about tramadol and it's complete bullshit.
If you have a gear habit you arn't going to feel much from tramadol. For most people without any tolerance 150mg will give you an enjoyable, pleasant all day buzz.
Yeah Slim, but it only lowers the threshold in 1% of the people who are ALREADY VULNERABLE TO SEIZURES and who TAKE AN ENORMOUS OVERDOSE. That doesn't mean it lowers the threshold in everyone who takes 150mg.
Obviously taking 700mg of tramadol is fucking stupid.
