i dont think many do that as the shops still manage to sell painkillers here in wales despite the scripts being free and only costing from 16p a packet anyway
add to that the decreased time off sick as people actualy can afford to get and take meds to get better I really dont see it is place to try and save money
As to NHS being crap on Wales i dont find it so they save my life on a regular baisis ( asthma )
