Opinions - Tramadol Extended Release (XR) - Recreational?

[Mish]

SWIM has recently come into some Tramadol tablets that are generics but XR versions of 100mg. SWIM knows that he could potentially crush them and bomb them to effectively get a "normal" Tramadol high, but SWIM was actually wondering if it were possible to in fact extend or prolong the high for a much longer period of time by taking multiple tabs at once....?

Has anyone ever done this, and if so - how many mg's did SWIY take?

This is quite a tricky drug to work out how to use the XR version recreationally and effectively; with the seizure risk being at 400mg+ and also making SWIM feel nauseous at doses of 400mg and above, SWIM wanted to make sure he was getting the right dose at the right time...

There is no information (at least, not solid information) on the mechanism of action for 100mg extended release tablets, i.e. how many mg's they release per hour or something.

SWIM was thinking that if SWIM took 400mg in one go (4 x 100mg Tramadol XR pills) then that might roughly equate to a dosage of 200mg, except lasting for a much longer time...? Would this be right, or do they work in a different way to that?

If anyone has any info at all that'd be greatly appreciated. In fact, if SWIY has info or personal experience on taking any XR versions of recreational pharmaceuticals (not by destroying the extended release attribute, but by higher dosing or something similar in order to prolong the high) then that too also be helpful for SWIM...

Thanks in advance
