I don't think Dr Collis or codeine cough linctus are available as OTC medicines even with a pharmacist present now you can buy pseudo codeine linctus, ie not the real thing.

I used to work for two doctors and it was amazing how they would pontificate about the over prescribing of certain medicines (notably antibiotics and benzos) yet when it was their sore throat or inability to sleep, then they took everything going!

I am downloading a brilliant 20 minute Penn and Teller programme called Bullshit - The War on Drugs. It makes some excellent points and is well worth viewing. I'll upload it onto my site when this torrent has finished and post a link.
