Oh yeah 2 of those will do the job, Ihad some of those once, 500mg standard looking paracetemol tabs with 30mg of codeine in each...so 60mg in total.... I reckon you could stab your self and not feel it...
on a nother drug note I accidentally (!) took a tarmazipan once, as i thought it was the same as diazipan my mate took when his back was bad (mine was too).... Went to sleep..... Woke up eventually...and my arm just kept missing the bedside table as it was a blur and a haze... Never been so spaced out in my life! And that was just one.
boy did I get a rollocking for that (missus is a Anaesthetist)
